[Info-vax] how to get the time of any timezone (C or VMS RTL/system services/etc.)

[Pierre]

hi,

for historical reasons, my machine time is UTC [I can not change
this].
is it possible using C or VMS RTL/system services/etc. to get the
"local time" (the one of my wall clock) ?
as all the logicals point to UTC, I must be able to specify the
requested timezone... :-/

I'm running VMS 7.3-2, 8.3, 8.4

TIA, Pierre
