Thanks for that. I think the following mods are needed:
months[tz.StandardDate.wMonth], changed to months[tz.StandardDate.wMonth-1], and months[tz.DaylightDate.wMonth], changed to months[tz.DaylightDate.wMonth-1], When I make these changes, the results are what I expect. I verified the info correlates with the following prog: http://17slon.com/gp/gp/gptimezone.htm FYI: my tsinfo output. (correct) ================================= Currently in Standard time Your current offset from GMT is -600 minutes Standard Time in your time zone is called AUS Eastern Standard Time Standard Time starts on the last Sunday in March Standard Time bias is 0 minutes Daylight Time in your time zone is called AUS Eastern Daylight Time Daylight Time starts on the last Sunday in October Daylight Time bias is -60 minutes ================================= Without my mods, I get: ================================= Currently in Standard time Your current offset from GMT is -600 minutes Standard Time in your time zone is called AUS Eastern Standard Time Standard Time starts on the last Sunday in April Standard Time bias is 0 minutes Daylight Time in your time zone is called AUS Eastern Daylight Time Daylight Time starts on the last Sunday in November Daylight Time bias is -60 minutes ================================= Clearly wrong.
