The clock is set to local time so there is no need to convert the time that is
retrieved. Some programs insert the time zone (-7 or -8 or PDT / PST) into
whatever output they are generating so this needs to be changed from standard /
daylight time. The standard time functions in OS/2 are DosGetDateTime() and
DosSetDateTime(), I think that the "set" stores the information in a control
block and the "get" just returns what was stored. The time zone parameter is
not set by OS/2 so some other program has to set it first.

I do know that IBM JAVA 131 is broken unless you use the short version of the
TZ variable. What other programs do not work correctly I don't know.

I think it is the clock program (which is an add on by Serenity) that does the
changes in eCS 1.2. Before that it was a third party program such as
TIME868.EXE.
