Summary: time module returns wrong timezone under windows
Initial Comment:
I have tested windows xp/2000 Chinese version with
python 2.3.3 and python 2.4b1.
My timezone in windows is GMT+8. But:
>>> import time
>>> time.timezone
-28800
-28800 means GMT-8, but not GMT+8. This cause
time.time() time.gmtime() return wrong values(16 hours
late).
I have no such problem under linux.
BTW, I found the issue:
https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1039270&group_id=5470
So I think maybe this problem is sensitive with my
Chinese platform too:
>>> time.tzname
('\xd6\xd0\xb9\xfa\xb1\xea\xd7\xbc\xca\xb1\xbc\xe4',
'\xd6\xd0\xb9\xfa\xb1\xea\x
d7\xbc\xca\xb1\xbc\xe4')

Closing as invalid, since there doesn't appear to be a Python
bug here.

Oh, I should set my linux time zone to GMT-8, which
represent the zone +0800, but not GMT+8. This is quite strange.
I learn it from this:
http://lists.debian.org/debian-chinese-gb/2002/07/msg00063.html
Thanks for your kind.

sorry, here is my linux /pro/version:
# more /proc/version
Linux version 2.4.25-1 (gcc version 3.3.3 (Debian
)) #1 SMP Wed Mar 10 13:10:05 GMT+8 2004
and more about date:
# date +%Z
GMT+8
# date +%z
-0800

Looks like. On my box,
$ date
Mon Oct 25 23:20:26 JST 2004
$ date -u
Mon Oct 25 14:20:27 UTF 2004
Just out of curiosity, what's your /proc/version?
You just say Linux, and don't give any further info.

Oh, is this a linux bug? See these two commands under linux:
# date
Mon Oct 25 22:06:58 GMT+8 2004
# date -u
Tue Oct 26 06:06:59 UTC 2004
the UTC time should be wrong.

Sorry, time should be right under Windows(my mistake :-( ).
Then since the result is quite different, maybe time is
wrong under Linux?
windows:
>>> import time
>>> time.timezone
-28800
>>> time.localtime()
(2004, 10, 25, 21, 28, 24, 0, 299, 0)
>>> time.gmtime()
(2004, 10, 25, 13, 28, 29, 0, 299, 0)
And Linux:
>>> import time
>>> time.timezone
28800
>>> time.tzname
('GMT+8', 'GMT+8')
>>> time.localtime()
(2004, 10, 25, 21, 28, 6, 0, 299, 0)
>>> time.gmtime()
(2004, 10, 26, 5, 28, 10, 1, 300, 0)

I am sure with my windows timezone setting. The time.tzname
is Chinese, which means 'Chinese Standard Time'. And China
is in GMT+8 zone.
Everything is ok under linux:
>>> import time
>>> time.tzname
('GMT+8', 'GMT+8')
>>> time.timezone
28800

No, look at the doc more carefully.
www.python.org/doc/current/lib/module-time.html
negative in most of Western Europe, positive in the US, zero
in the UK
If I remember correctly, China is on the opposite side of the
world from the US. :-)
> time.time() time.gmtime() return wrong values(16 hours

Reverify the time-zone with your Windows machine.
BTW, "Most-of-Western-Europe" doesn't seem clear to me at
all.
What's wrong with:
"negative in Asia, positive in the US, zero in the UK."
