#4 localtime() returns incorret is_dst

[Chris Nandor]

localtime() returns is_dst relative to current time,
independent of what the time passed to localtime is. So
after calling localtime(), is_dst will always be true no
matter that time I pass to localtime, if the current
time is in DST (and vice versa). This was a problem in
GUSI 1 too.

Sigh. This is bad, and pretty much uncorrectable. My only consolation is that I'm apparently in good company (I saw the same behavior on a Solaris system that I tested this on).

Yeah, I figured this would be the answer, as I noticed it was
in GUSI 1, and saw what the basic problem was after some
research in GUSI 2. Such is life, we've lived with it this
long. I will note it in perlport.
