[issue22932] email.utils.formatdate uses unreliable time.timezone constant

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

The proposed patch will not work on platforms that don't support tm_gmtoff.  A proper fix may look like this:

dt = datetime.fromtimestamp(timeval, timezone.utc)
if localtime:
  dt = dt.astimezone()
return format_datetime(dt, usegmt)
