I'm not convinced this is (was) a problem in anything other than the test
harness. It's merely a problem of how the date values are represented
internally. As long as the time zone doesn't change dynamically while
libcurl runs, libcurl will operate correctly.

Well, perhaps until then someone could identify exactly what the problem
and fix is...

That is of course just a work around, but fully acceptable as this problem
isn't very severe and quite tricky to solve.

Just remember that the problem is not solved jet and someday you need to
truly solve it.

I've committed the TZ=GMT patch in CVS.

Date: 2007-07-10 21:08
Sender: bagderProject AdminAccepting Donations


So I guess setting TZ to GMT (or perhaps something that isn't exactly the
same as UTC but still is a UTC-based timezone) unconditionally in the test
suite sounds like a good idea to at least avoid people getting these
failures.

ricce_n, any opinions?

I tried the <setenv> trick and it worked on Linux.

Date: 2007-07-08 20:58
Sender: dfandrich


What about forcing the time zone to GMT from the test harness when running
this (or all) scripts? This might be as simple as adding
<setenv>TZ=GMT</setenv> in the script, although it would need to be
verified on non-POSIX platforms.

i agree. I couldn't find a real solution without refactoring the test
expects for TAI timezones.

Sender: bagderProject AdminAccepting Donations


That's certainly not what the _test suite_ assumes. That's what libcurl,
its time+date parser and/or the underlying date functions assume.

Feel free to work on a fix, I personally have no plans on doing that
within the near future as I consider this a minor flaw effecting a rare
few.

TAI timezones adds leap seconds corrections.

Your test suite assumes that every day have exactly 24*60*60 seconds witch
is the case in UTC time but not in TAI.

See those pages for more info:

I have no idea how TAI time zones differ from UTC ones, and I also don't
see how libcurl bothers about timezones anywhere really (except for parsing
times) so what _can_ we do about this?
