I'm seeing an anomaly in the python time function on March 9, 2008 (the "spring foward" time):
>>> time.mktime((2008, 3, 9, 2, 59, 59, 0, 0, -1)) 1205049599.0 >>> time.mktime((2008, 3, 9, 3, 0, 0, 0, 0, -1)) 1205046000.0 Does anyone have an idea as to what might cause a 4000 seconds backwards jump on March 9th of last year? I would have expected 3600 seconds. Thanks, Lee P.S. A full program demonstrating the question: #!/usr/bin/env python import time, datetime d1 = datetime.datetime(2008, 3, 9, 2, 59, 0).timetuple() #!/usr/bin/env python import time, datetime d1 = datetime.datetime(2008, 3, 9, 2, 59, 0).timetuple() d2 = datetime.datetime(2008, 3, 9, 3, 0, 0).timetuple() t1 = time.mktime(d1) t2 = time.mktime(d2) print t1, t2 -- http://mail.python.org/mailman/listinfo/python-list
