[issue9798] time.tzset() doesn't properly reset the time.timezone variable

[Peter Simons]

New submission from Peter Simons <simons at cryp.to>:

Attached are two programs that I would expect to produce the same output, but they don't.

$ python --version
Python 2.6.5

$ cat test-timezone-1.py 
import os, time

os.environ["TZ"] = "Europe/Berlin"
time.tzset()
print "time.timezone =", time.timezone

os.environ["TZ"] = "Egypt"
time.tzset()
print "time.timezone =", time.timezone

$ cat test-timezone-2.py 
import os
from time import tzset, timezone

os.environ["TZ"] = "Europe/Berlin"
tzset()
print "timezone =", timezone

os.environ["TZ"] = "Egypt"
tzset()
print "timezone =", timezone

$ python test-timezone-1.py 
time.timezone = -3600
time.timezone = -7200

$ python test-timezone-2.py 
timezone = -3600
timezone = -3600
