2554 date limit

----
The 2554 date limit is a forthcoming date-related software limitation in the Apple File System (APFS).
Apple introduced APFS as part of macOS 10.13 in September 2017. It addressed the 2040 date limit of the previous HFS Plus format that had been in use on most Macintosh systems since 1998. However, APFS itself has a timestamp limit on July 21, 2554 at 23:34:33, after which the clock defined by its epoch will cycle back to January 1, 1970.Decoding the APFS file system by Kurt H. Hansen and Fergus Toolan, Norwegian Police University College. 2017-04-22. Revised 2017-06-21.
