I want to convert the current time to +0900 in Python.
What's the appropriate way to do this (assuming in the time module)?
I've read this isn't included with Python and you have to use something like pytz.
I don't want to change it on a server basis or globally, just in this one instance.
You can use the datetime module instead. Adapted from http://docs.python.org/library/datetime.html#datetime.tzinfo.fromutc
from datetime import tzinfo, timedelta, datetime
class FixedOffset(tzinfo):
def __init__(self, offset):
self.__offset = timedelta(hours=offset)
self.__dst = timedelta(hours=offset-1)
self.__name = ''
def utcoffset(self, dt):
return self.__offset
def tzname(self, dt):
return self.__name
def dst(self, dt):
return self.__dst
print datetime.now()
print datetime.now(FixedOffset(9))
Gives:
2011-03-12 00:28:32.214000
2011-03-12 14:28:32.215000+09:00
When I run it (I'm UTC-0500 for another day, then DST begins)
In the datetime module, there is an abstract base class called tzinfo which controls how datetime.datetime and datetime.time handle time zones. You basically derive your own class to control the time zone interpretation. I have never personally used it, so I can't say much more about it.
Unfortunately, the only time zone controls I see directly in the time module work on a global basis, I believe.
