Summary: time.mktime() doesn't raise exception
Initial Comment:
RH 6.2/alpha, egcs-2.91 , python 2.2.1c2:
import time
time.mktime((999999,)*9)
should raise and exception. It doesn't.
This is similar to bug 460357, where this
occurs on Sparc64.

This is a duplicate of #460357, so closing it as such.
This is not a serious problem; the test verifies that mktime
does not attempt to represent a date that is unrepresentable
(in a time_t). It turns out that the date selected is indeed
representable in a time_t on 64bit architectures, but not on
32-bit architectures.

Assigned to Barry and boosted priority -- please fix this
in a way you can live with. Neither C nor POSIX define the
range of time_t, and test_time's belief that test_mktime()
*should* raise OverflowError seems pure assumption to me.

Well, I don't know what mktime should do either :-/
Yes, there's a bug here. Tests shouldn't fail on 64bit
platforms (the same thing happens on IA64, too). I don't
know the issues well enough to fix it myself, though.

I guess I misunderstood the spec on time.mktime().
I was under the impression that if one of the
slots in the tuple, like seconds, was out of range,
then it should raise an exception. It doesn't and
it doesn't do it on RH7.1/i386/python 2.2 or
Win2k/i386/python 2.2.
But, in my defense, test_time says it *should* raise
an exception. Which is where I started.

Why should it? Isn't this just a bug in the test? (Not
rhetorical questions!)
