I'm trying to find my local UTF offset. For some reason, this is one hour too small (in absolute value):

$t = POSIX::mktime(localtime) - POSIX::mktime(gmtime);

I'm UTC -04:00, but that tells me that I'm only UTC -03:00. Can anyone explain why? (if it matters, I'm on Debian with "v5.8.4 built for i386-linux-thread-multi")

Update: I was being an idiot and was actually getting -05:00 instead of -04:00. Anyhow, the solution is to do

@g=gmtime;$g[8]=-1;$offset=POSIX::mktime(localtime)-POSIX::mktime(@g);

Since gmtime won't set DST, and when you're in it, that will mess you up (since mktime() takes local time, which in a DST timezone, expects to be in DST).


With humble thanks,
