Maybe.  If they depend on some specific behavior on a platform that offers
it, then yes, there could be issues.  But since the docs are so vague if
it does break code it will most likely be because someone didn't follow
the warnings in the spec.

And while we are on this subject, does anyone have any issues if I cause
_strptime to recognize UTC and GMT as timezones?  The Solaris box I always
use to do libc strptime comparisons to does not recognize it as an
acceptable value for %Z, but since it is a known fact that neither have
daylight savings I feel _strptime should recognize this fact and set the
daylight savings value to 0 insteading of raising an error saying it
doesn't know about that timezone.

Any objections to the change?
