Forcing automatic timezone discovery with pyobjc on OS X

autotimezone.m

# Tested on 10.11
# Assumes your network is in a state to actually do the discovery and that you have
# automatic timezone discovery enabled in Date & Time and Location services enabled
# (Generally this means wifi enabled on your device and network stack is up)

# For enabling location services and auto, check Allister's work here:
# https://gist.github.com/arubdesu/b72585771a9f606ad800
