There is/are 4940 day(s) and 4 hour(s) left before the clock used by Unix and Mac OS X 10.5.8 and older
expires on January 19, 2038 at 03:14:07

The 2038 date limit is a forthcoming Unix-based software limitation of Mac OS X versions prior to 10.6.

As the Mac OS X operating system was based on NeXTSTEP, a Unix-based derivative developed at NeXT, early versions shared the 32-bit date range to define its epoch. This limitation would cause the computer clock to cycle from January 19, 2038 at 03:14:07 back to January 1, 1970. Mac OS X 10.6 overcame this with 64-bit support.[1] However, it was still using HFS Plus as its primary drive format, which itself had a 2040 date limit. This was addressed in September 2017 with the introduction of the Apple File System (APFS) in macOS 10.13.[2]
