hi all, sorry if i'm reposting
why time.strptime and time.localtime returns tuple with different DST (9 item of the tuple)?
is there some of setting to fix the problem?
Python 2.2.3 (#1, May 31 2005, 11:33:52)
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information. import time
time.strptime("2005-06-07 21:00:00", "%Y-%m-%d %H:%M:%S")
(2005, 6, 7, 21, 0, 0, 6, 1, 0) time.localtime()
(2005, 6, 7, 21, 2, 39, 1, 158, 1)

mailto: ka*****@i.com.ua 10  2297  http://docs.python.org/lib/module-time.html tells us the last element
is the DST flag, on your computer that applies for localtime(). To get
this with strptime() you have to tweak the %Z formatter - this is
platform specific.
Like the last poster said, use %Z. On my Mandriva Linux system I get the
following results: time.localtime()
(2005, 6, 7, 15, 7, 12, 1, 158, 1) time.strptime("2005-06-07 15:07:12 EDT", "%Y-%m-%d %H:%M:%S %Z")
(2005, 6, 7, 15, 7, 12, 1, 158, 1)

i've check the value of time.tzname:

In your case it is the EEST, as this is the DST timezone (see again: http://docs.python.org/lib/module-time.html)

seems like it is not a platform specific,
i think to solve the problem i need put settings in order (in php it is php.ini file) thus i'll have a portable code.
i've check the following code on my various servers, and it gives me different results:
import time
time.tzname
time.daylight
time.strptime("2005-06-07 15:07:12", "%Y-%m-%d %H:%M:%S")

yes, i agree, on my WinXP it gives another values.
but my question is how to setup the python (or OS) to make it gives the same results when i call
time.strptime("2005-06-07 15:07:12", "%Y-%m-%d %H:%M:%S")
on various servers (and maybe with various OS)?
for now, i can't get it even with the same OS.
and i would like to set time string exactly as "2005-06-07 15:07:12", without "CEST", "EEST" and so on, because as you've notice before, it is different on a variuos systems wi******@hotmail.com wrote: The names are at least platform specific, see below the names of the

It is probably the best to calculate back to UTC.
Assume "2005-06-07 15:07:12" the local time, then convert it as
follows to UTC. Use the UTC time to store/manipulate/whatever you want
to do.
import time
t = time.mktime(time.strptime("2005-06-07 15:07:12", "%Y-%m-%d
%H:%M:%S"))
print time.ctime(t)
offset = time.timezone
if time.daylight:
offset = time.altzone
t += offset
print time.ctime(t)
maybe you are right, i've searched in google groups - such a question was posted to comp.lang.python many times and i has not found (yet) the answer on "how to tune up the output of time.strptime()?" wi******@hotmail.com wrote: It is probably the best to calculate back to UTC.

I've been bitten by the quirks in the time modules so many times
that I would advice against using it for any date handling. It's
ok for time measurement as long as you understand the differences
between time.clock and time.time on your particular platform. You
should be aware that it's just a thin wrapper around the c libs,
and they seem to disagree wildly among platforms on how things
should be done. On NT 4 for instance, the C time libs was a few
weeks off concerning when DST starts in Europe (but the win32 API
was correct), time zone names vary among platforms etc. There is
an inverse of localtime() in mktime(), but no inverse of gmtime()
etc. Yuk!
I would suggest that you either update Python to 2.4 (or 2.3) and
use the datetime module, or that you get mxDateTime if you are
stuck with 2.2. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
