I get
time data \'19/Apr/2011:22:12:39\' does not match format \'%d/%b/%y:%H:%M:%S\'
when using datetime.strptime(\'19/Apr/2011:22:12:39\
datetime.strptime(\'19/Apr/2011:22:12:39\
Try %d/%b/%Y:%H:%M:%S instead - %y right now means 11.
%d/%b/%Y:%H:%M:%S
%y
You can "debug" datetime formats easily using date (on the shell and not on python, I mean, assuming you're running GNU/Linux or similar):
date
date '+%d/%b/%Y:%H:%M:%S' 05/May/2011:09:00:41
