The <a href="/wiki/Integer_overflow" title="Integer overflow">overflow</a> error will occur at 03:14:08 UTC on 19 January 2038.</figcaption></figure>
<p>The <b>year 2038 problem</b> (also known as <b>Y2038</b>,<sup id="cite_ref-:0_1-0" class="reference"><a href="#cite_note-:0-1">&#91;1&#93;</a></sup> <b>Y2K38</b>, <b>Y2K38 superbug</b> or the <b>Epochalypse</b><sup id="cite_ref-2" class="reference"><a href="#cite_note-2">&#91;2&#93;</a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3">&#91;3&#93;</a></sup>) is a <a href="/wiki/Time_formatting_and_storage_bugs" title="Time formatting and storage bugs">time computing problem</a> that leaves some computer systems unable to represent times after 03:14:07 <a href="/wiki/Coordinated_Universal_Time" title="Coordinated Universal Time">UTC</a> on 19&#160;January&#160;2038.
</p><p>The problem exists in systems which measure <a href="/wiki/Unix_time" title="Unix time">Unix time</a> – the number of seconds elapsed since the <i>Unix <a href="/wiki/Epoch_(computing)" title="Epoch (computing)">epoch</a></i> (00:00:00 UTC on 1&#160;January&#160;1970) – and store it in a <a href="/wiki/Integer_(computer_science)" title="Integer (computer science)">signed 32-bit integer</a>. The data type is only capable of representing integers between −(2<sup>31</sup>) and <a href="/wiki/2,147,483,647" title="2,147,483,647">2<sup>31</sup> − 1</a>, meaning the latest time that can be properly encoded is 2<sup>31</sup> − 1 seconds after epoch (03:14:07 UTC on 19&#160;January&#160;2038). Attempting to increment to the following second (03:14:08) will cause the <a href="/wiki/Integer_overflow" title="Integer overflow">integer to overflow</a>, setting its value to −(2<sup>31</sup>) which systems will interpret as 2<sup>31</sup> seconds <i>before</i> epoch (20:45:52 UTC on 13&#160;December&#160;1901). The problem is similar in nature to the <a href="/wiki/Year_2000_problem" title="Year 2000 problem">year 2000 problem</a>. Analogous storage constraints for unsigned 32-bit integers will be reached in <a href="/wiki/Time_formatting_and_storage_bugs#Year_2106" title="Time formatting and storage bugs">2106</a>.
</p><p>Computer systems that use time for critical computations may encounter fatal errors if the year 2038 problem is not addressed. Some applications that use future dates have already encountered the bug. The most vulnerable systems are those which are infrequently or never updated, such as <a href="/wiki/Legacy_system" title="Legacy system">legacy</a> and <a href="/wiki/Embedded_system" title="Embedded system">embedded systems</a>. To address the problem, many modern systems have been upgraded to measure Unix time with signed <a href="/wiki/64-bit_computing" title="64-bit computing">64-bit</a> integers instead, which will take 292 billion years to overflow—approximately 21 times the estimated <a href="/wiki/Age_of_the_universe" title="Age of the universe">age of the universe</a>.

<p>Many computer systems measure time and date as <a href="/wiki/Unix_time" title="Unix time">Unix time</a>, an international standard for digital timekeeping. Unix time is defined as the number of seconds elapsed since 00:00:00 <a href="/wiki/Coordinated_Universal_Time" title="Coordinated Universal Time">UTC</a> on 1 January 1970 (an arbitrarily chosen time based on the creation of the first <a href="/wiki/Unix" title="Unix">Unix system</a>), which has been dubbed the <i>Unix epoch</i>.<sup id="cite_ref-CNMP-H-78-KY-M-Leviticus25:35-37_4-0" class="reference"><a href="#cite_note-CNMP-H-78-KY-M-Leviticus25:35-37-4">&#91;4&#93;</a></sup>
</p><p>Unix time has historically been encoded as a <a href="/wiki/Integer_(computer_science)" title="Integer (computer science)">signed 32-bit integer</a>, a data type composed of 32 <a href="/wiki/Bit" title="Bit">binary digits</a> (bits) which represent an integer value, with 'signed' meaning that the number can represent both positive and negative numbers, as well as zero; and is usually stored in <a href="/wiki/Two%27s_complement" title="Two&#39;s complement">two's complement</a> format.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5">&#91;a&#93;</a></sup> Thus, a signed 32-bit integer can only represent integer values from −(2<sup>31</sup>) to <a href="/wiki/2,147,483,647" title="2,147,483,647">2<sup>31</sup> − 1</a> inclusive. Consequently, if a signed 32-bit integer is used to store Unix time, the latest time that can be stored is 2<sup>31</sup> − 1 (2,147,483,647) seconds after epoch, which is 03:14:07 on Tuesday, 19 January 2038.<sup id="cite_ref-spinellis_6-0" class="reference"><a href="#cite_note-spinellis-6">&#91;5&#93;</a></sup> Systems that attempt to increment this value by one more second to 2<sup>31</sup> seconds after epoch (03:14:08) will suffer <a href="/wiki/Integer_overflow" title="Integer overflow">integer overflow</a>, inadvertently flipping the sign bit to indicate a negative number. This changes the integer value to −(2<sup>31</sup>), or 2<sup>31</sup> seconds <i>before</i> epoch rather than <i>after</i>, which systems will interpret as 20:45:52 on Friday, 13 December 1901. From here, systems will continue to count up, toward zero, and then up through the positive integers again. As many computer systems use time computations to run critical functions, the bug may introduce fatal errors.

<p>Any system using <a href="/wiki/Data_structure" title="Data structure">data structures</a> with 32-bit time representations has an inherent risk to fail.

<p><a href="/wiki/Embedded_system" title="Embedded system">Embedded systems</a> that use dates for either computation or diagnostic logging are most likely to be affected by the Y2038 problem.<sup id="cite_ref-:0_1-1" class="reference"><a href="#cite_note-:0-1">&#91;1&#93;</a></sup> Despite the modern <a href="/wiki/Moore%27s_law" title="Moore&#39;s law">18–24 month generational update in computer systems technology</a>, embedded systems are designed to last the lifetime of the machine in which they are a component. It is conceivable that some of these systems may still be in use in 2038. It may be impractical or, in some cases, impossible to upgrade the software running these systems, ultimately requiring replacement if the 32-bit limitations are to be corrected.
</p><p>Many transportation systems from flight to automobiles use embedded systems extensively. In automotive systems, this may include <a href="/wiki/Anti-lock_braking_system" title="Anti-lock braking system">anti-lock braking system</a> (ABS), <a href="/wiki/Electronic_stability_control" title="Electronic stability control">electronic stability control</a> (ESC/ESP), <a href="/wiki/Traction_control_system" title="Traction control system">traction control</a> (TCS) and automatic <a href="/wiki/Four-wheel_drive" title="Four-wheel drive">four-wheel drive</a>; aircraft may use <a href="/wiki/Inertial_navigation_system" title="Inertial navigation system">inertial guidance systems</a> and <a href="/wiki/Satellite_navigation_device" title="Satellite navigation device">GPS receivers</a>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7">&#91;b&#93;</a></sup> Another major use of embedded systems is in communications devices, including cell phones and Internet-enabled appliances (e.g. <a href="/wiki/Router_(computing)" title="Router (computing)">routers</a>, <a href="/wiki/Wireless_access_point" title="Wireless access point">wireless access points</a>, <a href="/wiki/IP_camera" title="IP camera">IP cameras</a>) which rely on storing an accurate time and date and are increasingly based on Unix-like operating systems. For example, the Y2038 problem makes some devices running 32-bit <a href="/wiki/Android_(operating_system)" title="Android (operating system)">Android</a> crash and not restart when the time is changed to that date.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8">&#91;6&#93;</a></sup>
</p><p>However, this does not imply that all embedded systems will suffer from the Y2038 problem, since many such systems do not require access to dates. For those that do, those systems which only track the difference between times/dates and not absolute times/dates will, by the nature of the calculation, not experience a major problem. This is the case for automotive diagnostics based on legislated standards such as CARB (<a href="/wiki/California_Air_Resources_Board" title="California Air Resources Board">California Air Resources Board</a>).<sup id="cite_ref-9" class="reference"><a href="#cite_note-9">&#91;7&#93;</a></sup>

<p>In May 2006, reports surfaced of an early manifestation of the Y2038 problem in the <a href="/wiki/AOLserver" title="AOLserver">AOLserver</a> software. The software was designed with a <a href="/wiki/Kludge" title="Kludge">kludge</a> to handle a database request that should "never" time out. Rather than specifically handling this special case, the initial design simply specified an arbitrary <a href="/wiki/Timeout_(computing)" title="Timeout (computing)">time-out</a> date in the future. The default configuration for the server specified that the request should time out after one billion seconds. One billion seconds (just over 31 years, 251 days, 1 hour, 46 minutes and 40 seconds) after 01:27:28&#160;UTC on 13 May 2006 is beyond the 2038 cutoff date. Thus, after this time, the time-out calculation overflowed and returned a date that was actually in the past, causing the software to crash. When the problem was discovered, AOLServer operators had to edit the configuration file and set the time-out to a lower value.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10">&#91;8&#93;</a></sup><sup id="cite_ref-11" class="reference"><a href="#cite_note-11">&#91;9&#93;</a></sup>

<p>There is no universal solution for the Year 2038 problem. For example, in the <a href="/wiki/C_(programming_language)" title="C (programming language)">C language</a>, any change to the definition of the <code><a href="/wiki/Time_t" class="mw-redirect" title="Time t">time_t</a></code> data type would result in <a href="/wiki/Binary-code_compatibility" title="Binary-code compatibility">code-compatibility</a> problems in any application in which date and time representations are dependent on the nature of the signed 32-bit <code>time_t</code> integer. For example, changing <code>time_t</code> to an unsigned 32-bit integer, which would extend the range to 2106 (specifically, 06:28:15 UTC on Sunday, 7 February 2106), would adversely affect programs that store, retrieve, or manipulate dates prior to 1970, as such dates are represented by negative numbers. Increasing the size of the <code>time_t</code> type to 64 bits in an existing system would cause incompatible changes to the layout of structures and the binary interface of functions.
</p><p>Most operating systems designed to run on 64-bit <a href="/wiki/Hardware_architecture" title="Hardware architecture">hardware</a> already use signed 64-bit <code>time_t</code> integers. Using a signed 64-bit value introduces a new wraparound date that is over twenty times greater than the estimated <a href="/wiki/Age_of_the_universe" title="Age of the universe">age of the universe</a>: approximately 292&#160;billion years from now.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12">&#91;10&#93;</a></sup> The ability to make <a href="/wiki/Computation" title="Computation">computations</a> on dates is limited by the fact that <code>tm_year</code> uses a signed 32-bit integer value starting at 1900 for the year. This limits the year to a maximum of 2,147,485,547 (2,147,483,647 + 1900).<sup id="cite_ref-13" class="reference"><a href="#cite_note-13">&#91;11&#93;</a></sup>
</p><p>Alternative proposals have been made (some of which are already in use), such as storing either <a href="/wiki/Millisecond" title="Millisecond">milliseconds</a> or <a href="/wiki/Microsecond" title="Microsecond">microseconds</a> since an epoch (typically either 1 January 1970 or 1 January 2000) in a signed 64-bit integer, providing a minimum range of 300,000 years at microsecond resolution.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14">&#91;12&#93;</a></sup><sup id="cite_ref-15" class="reference"><a href="#cite_note-15">&#91;13&#93;</a></sup> In particular, Java's use of 64-bit long integers everywhere to represent time as "milliseconds since 1 January 1970" will work correctly for the next 292 million years. Other proposals for new time representations provide different precisions, ranges, and sizes (almost always wider than 32 bits), as well as solving other related problems, such as the handling of <a href="/wiki/Leap_second" title="Leap second">leap seconds</a>. In particular, TAI64<sup id="cite_ref-16" class="reference"><a href="#cite_note-16">&#91;14&#93;</a></sup> is an implementation of the <a href="/wiki/International_Atomic_Time" title="International Atomic Time">International Atomic Time</a> (TAI) standard, the current international real-time standard for defining a second and frame of reference.
