[Python-Dev] Broken strptime in Python 2.3a1 & CVS

[Kevin Jacobs]

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
