Issue 1234123: datetime.strftime %s - Python tracker (original) (raw)

I don't know if this is a bug in datetime or in pytz, so I submitted this as a bug with pytz as well: https://sourceforge.net/tracker/index.php?func=detail&aid=1233776&group_id=79122&atid=555590

The first example does not give the result I expect. The second does.

Python 2.3.4 (#1, Aug 6 2004, 18:12:39) [GCC 2.95.3 20010315 (SuSE)] on linux2

from datetime import datetime from pytz import timezone utc = timezone('UTC') utc_dt = datetime(1970, 1, 1, 0, 0, 0, tzinfo=utc) print utc_dt 1970-01-01 00:00:00+00:00 print utc_dt.strftime('%c * %Z * %s') Thu Jan 1 00:00:00 1970 * UTC * -3600

Given that tzinfo is coming from the pytz package, which is external to Python, it seems unlikely that this is a Python bug. If the pytz developers ultimately track down the problem to a Python bug, they can surely provide a test case for Python that doesn't depend on external software.

Closing this bug; it can be reopened if it turns out to be a Python problem.
