[pypy-issue] [issue986] Problems with timezones in datetime.datetime

[Dan Villiom Podlaski Christiansen]

New submission from Dan Villiom Podlaski Christiansen <danchr at gmail.com>:

Try running the following little script:

=========
import datetime, os, time

os.putenv('TZ', 'GMT')

def bug():
  ct = time.time()
  delta = (datetime.datetime.utcfromtimestamp(ct) -
           datetime.datetime.fromtimestamp(ct))

  return delta.days * 86400 + delta.seconds

print ' '.join(str(bug()) for x in xrange(10))
===========

Under CPython I get:

===========
0 0 0 0 0 0 0 0 0 0
===========

Under PyPy 1.7 as well as the latest nightly I get something like:

===========
0 -1 0 -1 0 0 0 0 -1 0
===========

This is somewhat unexpected.
