New submission from Kevin Barnhart <barnbu...@gmail.com>: Just starting to dabble in the world of time and datetime objects. I was converting an array of datetime objects to an array of floats via mktime to do some data analysis. I have ran into an issue where mktime seems to be adding an hour on April 6, 2003. Attached is an example script which I used to create the below output:
Python version: (2, 6, 5, 'final', 0) Epoch: time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0) First datetime: 2003-04-06 02:58:17 Second datetime: 2003-04-06 03:13:17 Is first datetime prior to second?: True First datetime, time struct: time.struct_time(tm_year=2003, tm_mon=4, tm_mday=6, tm_hour=2, tm_min=58, tm_sec=17, tm_wday=6, tm_yday=96, tm_isdst=-1) Second datetime, time struct: time.struct_time(tm_year=2003, tm_mon=4, tm_mday=6, tm_hour=3, tm_min=13, tm_sec=17, tm_wday=6, tm_yday=96, tm_isdst=-1) Is first time struct prior to second?: True First timestamp generated by mktime: 1049623097.0 Second timestamp generated by mktime: 1049620397.0 Is first timestamp less than second timestamp?: False First recovered datetime: 2003-04-06 03:58:17 Second recovered datetime: 2003-04-06 03:13:17 Is first recovered prior to second recovered?: False Is first recovered datetime same as original?: False Is second recovered datetime same as original?: True ---------- files: mktimeissue.py messages: 118662 nosy: barnburnr priority: normal severity: normal status: open title: mktime adding an hour in April (naive struct)? type: behavior Added file: http://bugs.python.org/file19232/mktimeissue.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10102> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
