Subject: Question of time :-)
I don't know if this is correct address to send this to, but
I hope you'll be able to redirect me in case it's not :-)
In my application I need to know, the time difference
between any given time in any given timezone, and UTC. Is
this possible to do WITHOUT changing the TZ environment
variable? I cannot do this, because this is in a multithreaded
program, and changing TZ would affect other threads.
I cannot fork another process, as this takes too much time
I need a program, that does sth. like this:
> echo $TZ
Tue Apr 7 18:31:42 MET DST 1998
> calculateUtcDifference "1.2.1998 12:13 EST"
I would be great if you knew a portable solution
Thanx in advance
