The tzparse Module

(Obsolete) The (highly incomplete) tzparse module contains a parser for time zone specifications. When you import this module, it parses the content of the TZ environment variable; Example 14-31 demonstrates.

Example 14-31. Using the tzparse Module

File: tzparse-example-1.py

import os
if not os.environ.has_key("TZ"):
    # set it to something...
    os.environ["TZ"] = "EST+5EDT;100/2,300/2"

# importing this module will parse the TZ variable
import tzparse

print "tzparams", "=>", tzparse.tzparams
print "timezone", "=>", tzparse.timezone
print "altzone", "=>", tzparse.altzone
print "daylight", "=>", tzparse.daylight
print "tzname", "=>", tzparse.tzname

tzparams => ('EST', 5, 'EDT', 100, 2, 300, 2)
timezone => 18000
altzone => 14400
daylight => 1
tzname => ('EST', 'EDT')

In addition to the variables shown in Example 14-31, this module contains a number of time manipulation functions that use the defined time zone.
