And from the same description you can see that the actual strings being used to name the standard and the DST periods (CET and CEST in the example above) have no meaning to the system. You can set them to anything you want without influencing the behaviour. The strings are only meant to show something meaningful to users. The first string is mandatory. The second string, in addition to be meant for the user, is also a flag to tell the system to apply DST according to the standard rules (mentione above), or by the rules specified. So, with TZ=WINTER-1SUMMER,M3.5.0/2:00,M10.5.0/3:00 date '%a %b %e %T %Z %Y' will display Fr Nov 4 08:26:17 WINTER 2016 today, but had displayed Fr Oct 28 08:26:17 SUMMER 2016 last week. --Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
