>[SNIP[]]The 64-bit timestamps used by NTP consist of a 32-bit part for seconds and a 32-bit part for fractional second, giving NTP a time scale that rolls over every 2[SUP[32]] seconds (136 years) and a theoretical resolution of 2[SUP[−32]] second (233 picoseconds). NTP uses an epoch of 1 January 1900. The first rollover occurs in 2036, prior to the UNIX year 2038 problem.[SNIP[]]
