The Unix Epoch is janu0:00 UTC (by definition of (time_t)0), In my time zone (MET= Paris/France) the same Epoch is Thu Jan 1 01:00.The NZN® GPS-Synchronized Digital Message Clock receives a time signal transmitted daily by a GPS receiver via Radio Frequency Switcher. It uses the time signal to automatically adjust itself, if necessary, to ensure accurate and synchronized time throughout the entire facility. some time_t) measured from the Epoch (like the result of time(2), gettimeofday, clock_gettime with CLOCK_REALTIME) has no time zone. The notion of time zone is only relevant for struct tm as returned by localtime & gmtime (and related) functions. I don't understand the logic of people taking more time to ask the question here that to look -just by typing man clock_gettime on their Linux box- into the man pages). (I'm quite sadly surprised by the number of questions here which could be answered very quickly by looking into the man. CLOCK_MONOTONIC), the used origin is not specified. It depends upon the clk_id you are asking for, and for CLOCK_REALTIME, the time is measured since the Unix Epoch. It is a bit like saying that two, deux, 1+1, or 2, or 10b -with b meaning binary- are all representations of the same number.īack to the question, the man page of clock_gettime gives the precise answer to the question. Only the display (or shown form) of that time changes. Unix (and Posix) convention is to measure it from the Epoch (start of 1970, as aix's answer explains).ĭisplaying some time in UTC, or local time, or using the French revolutionary calendar, or using the Maya calendar, or any other calendar from whatever culture you are interested in, does not change that time. See time(7) for an overview of time-related functions.Īny clock device returns a time measured from some origin event in the past. Actually, the question does not make a lot of sense.
