2036 date limit

----
The 2036 date limit is a forthcoming limitation of early versions of the Network Time Protocol (NTP) used by classic Mac OS and older versions of Mac OS X and Unix.
The 64-bit timestamp used by NTPv3 and earlier will cycle from February 7, 2036 at 06:28:16 back to January 1, 1900.A look at the Year 2036/2038 problems and time proofness in various systems by sturmflut, LieberBiber. 2017-03-14. The NTPv4 specification was proposed in 2010 to address the issue by adopting a 128-bit value. Due to security concerns, Apple no longer relies on NTP as of macOS Mojave (10.14) in 2018 and instead implemented its own timed function.If Mojave doesn't include ntpd, how do Mojave systems keep time in sync? by John Lockwood, Apple Communities. 2019-03-22.
