UTC seems to be incorrect. #45

When I leave the TZ offset commented out, the local clock is 5 hours behind UTC (and UTC reports what is the local time).
When I set the TZ offset to +0500 to match the local time, UTC reports 5 hours ahead of what UTC really is.

The time of creation of this ticket, where I am, is ~20:44 London Time (identical with UTC right now). But with the +5 offset, this is what my console reports:

/d t
/ IEE136I LOCAL: TIME=20.39.27 DATE=2023.082  UTC: TIME=01.39.27 DATE=2023.083

Hi Greg,

the parameter in the config file seems to be the setting for daylight saving time:

TZOFFSET 0100 # daylight savings time in effect

To have 'your' time zone set properly, you need to set it in SYS1.PARMLIB(PARMTZ) . I replaces the standard 'W,05' by 'E,01' as I'm sitting in Germany - and it works well. Nex week, I'll activate the daylight saving line in the conf file -that's it.

Regards, Harm
