<snip> Alas, UNIX doesn't do leap seconds; forbidden by POSIX; always uses UTC. <snip> If it doesn't do leap seconds, then it must be GMT, right? Isn't UTC = GMT + LEAP_Seconds? I ask this because a few months ago I made changes to most of the "MVS" based code in a product to have it use IBM services and NOT "STCK and then do arithmetic". We were finding that our time stamps were off by about 22 seconds (compared to what the system was doing with WTOs) where an ETR tied to GPS (they use UTC) was in use.
