What was more interesting was seeing his IRC comments while coding a replacement... It seems POSIX is quite brain-dead in this area - ignoring daylight savings, normalising the time struct, and generally being 'helpful' :-). (Of course, GMT is never on daylight savings).

It's in the single unix spec and in the ISO C spec. Jeremy
RE: Samba 3.0 alpha 20 problem with timegm->mktime() on HP-UX
I have already included a fix for this which you could try. See previous
e-mail to Andrew and samba-technical attached. Hopefully this will be
adopted as a fix at some stage.
Andrew,
Another suggestion which appears to work without a kludge is a very minor
mod to the code originally contributed by Roger Beeman <[EMAIL PROTECTED]>,
with the help of Mark Baushke <[EMAIL PROTECTED]> and the rest of the Gurus at
CISCO. Further improved by Roger with assistance from Edward J. Sabol based
on input by Jamie Zawinski.
Setting this as a timegm replacement within lib/replace.c overcomes the need
to reset TIMEZONE.
time_t timegm(struct tm *t)
{
time_t tl, tb;
struct tm *tg;
tl = mktime (t);
if (tl == -1)
{
t->tm_hour--;
tl = mktime (t);
if (tl == -1)
return -1; /* can't deal with output from strptime */
tl += 3600;
}
tg = gmtime (&tl);
tg->tm_isdst = 0;
tb = mktime (tg);
if (tb == -1)
{
tg->tm_hour--;
tb = mktime (tg);
if (tb == -1)
return -1; /* can't deal with output from gmtime */
tb += 3600;
}
return (tl - (tb - tl));
}

Subject: Samba 3.0 alpha 20 problem with timegm->mktime() on HP-UX
Hi
I had a problem with net ads join on HP-UX. I used mktime() instead of the
timegm() that was used in Samba 3.0 alpha 20.
net ads join gives error saying that the times are out of sync (Windows 2000
DC and Samba HP Unix Box)
But they are in perfectly in sync. mktime() interprets the time as local
time (PST8PDT). You need to set the TZ environment variable to GMT to solve
the problem and get it working.
If I come up with a programatic solution to this issue, I will leave it on
the mailing list.
