Unix is in fact older than UTC. > They have always counted the non-leap > seconds since 1970-01-01. The Posix interpretation is only a few years old, and a break with Unix history. Before that, time_t ticked SI seconds since the epoch (i.e. 1970-01-01:00:00:00 GMT = 1970-01-01:00:00:10 TAI). The time(2) man page in the Sixth Edition (unchanged in the Seventh) of Research Unix says: .I Time returns the time since 00:00:00 GMT, Jan. 1, 1970, measured in seconds. IOW, it is a count of elapsed time since a certain moment, measured in SI seconds, and not an encoding of anything. Even today, you can install the ADO (and probably GNU) packages in either of two ways: "posix", in which there are no leap seconds and time_t's get the POSIX interpretation you reference; and "right", in which there are leap seconds and time_t is a count of seconds. Try setting your TZ to "right/<whatever>" and see what you get. -- You escaped them by the will-death John Cowan and the Way of the Black Wheel.
