Description
salt.states.timezone.system produces an error when trying to set on windows systems

Setup
America/New_York:
timezone.system

-or-
America/New_York:
timezone.system:
- utc: True

Steps to Reproduce the behavior
applying either of the above as a state works correctly on linux.
applying either of the above as a state on Windows sets the timezone, but then it outputs as an error:

      ID: America/New_York
Function: timezone.system
  Result: False
 Comment: Failed to set UTC to True
 Started: 16:09:07.944704
Duration: 0.0 ms
 Changes:   

Expected behavior
expected behavior is that salt.states.timezone.system should succeed without errors on windows systems. perhaps the utc parameter should not apply to windows systems.
