- In several parts of the world Daylight Saving Time is observed during summer. When winter comes it is reversed. The timezone class does not support any scheme like DST which makes the UTC offset different for different periods of the year. Hence this method always returns None.
# An example Python program printing the available DST information from a # timezone instance
# import the classes
# Create time
# Print the time
# Will return None as long as DST is not supported
