[Python-Dev] Broken strptime in Python 2.3a1 & CVS (original) (raw)

Hi all,

I've just noticed a problem in one of our financial systems that was caused by the new pure-Python strptime module by Brett Cannon. This was a test system, so I suppose it was doing its job. SourceForge won't currently let me login (big surprise there!) so I'm posting on python-dev for now.

Test script: import time n = time.strptime('7/1/2002', '%m/%d/%Y') print 'Time tuple:',n m = time.mktime(n) print 'Seconds from epoch:',m print 'Formatted local time:',time.strftime('%m/%d/%Y', time.localtime(m))

Python 2.2.2: Time tuple: (2002, 7, 1, 0, 0, 0, 0, 182, 0) Seconds from epoch: 1025499600.0 Formatted local time: 07/01/2002

Python 2.3-cvs (with #undef HAVE_STRPTIME hard-coded): Time tuple: (2002, 7, 1, -1, -1, -1, 0, 182, -1) Seconds from epoch: 1025492339.0 Formatted local time: 06/30/2002

Our financial system does really strange things when dates don't round-trip properly. It is running on a large IA32 Redhat Linux 8.0 system with the latest Python CVS.

Thanks, -Kevin
