What will happen to Unix time in 2038?

If you have read How Bits and Bytes Work, you know that a signed 4-byte integer has a maximum value of 2,147,483,647, and this is where the Year 2038 problem comes from. The maximum value of time before it rolls over to a negative (and invalid) value is 2,147,483,647, which translates into January 19, 2038.

What is Unix 32-bit time?

All 32-bit Unix/Linux-based systems store the system clock time internally as the number of seconds since the “Epoch.” The latest time and date that can be represented as seconds-since-the-Epoch in that 32-bit signed integer is 3:14:07 UTC on Tuesday, January 19, 2038.

What is the largest UTC time that can be encoded by software with the y2k38 bug?

The highest value that can be represented using these 31 bits is 2,147,483,647 and what this number will represent in time_t is equal to 19 January, 2038 at 03:14:07 UTC.

What will happen on 2038?

The counter will then begin to count from the negative scale, once this date comes to pass, causing the computers to reset to December 13th 1901, leading to all kinds of errors in every modern 32-bit computer. This is the 2038 problem, which will mark the end of UNIX time and subsequently the UNIX epoch.

Does Linux have a 2038 problem?

The forthcoming Linux 5.10 looks like it will include further fixes for the Year 2038 problem, aka Y2K38. The flaw means that many systems can’t conceive of dates beyond 03:14:07 UTC on 19 January 2038.

How was Y2K solved?

Software and hardware companies raced to fix the bug and provided “Y2K compliant” programs to help. The simplest solution was the best: The date was simply expanded to a four-digit number. Governments, especially in the United States and the United Kingdom, worked to address the problem.

Will there be another Y2K?

When the year 10000 (Y10k) rolls around, we’ll have the Y2K problem all over again when we try to subtract 9000 from 0000. If 8,000 years is too far in the future, don’t worry! There’s another giant date bug that’s right around the corner in 2038.

Will Unix time run out?

The most imminent overflow date is the 32-bit signed integer-based systems’, scheduled for 19 January 2038, at 03:14:07 UTC.
