# This script make the event it is attached to (not global!)
# trigger a connected value at specific moment of year/day.
# It will behave as if a button was "pushed" when entering period
# and "release" after the period. Typical use is to use it as
# event_time on a living object (that objects that triggers
# time events). 
# This script ensure button remains pushed for all period, and 
# get release after period. This works even is map is loaded
# in middle of period or map gets released from memory and put in 
# cache. In those case, event will just ensure that "current" state 
# correspond to expected state and correct status if needed.
# Note: the event must be inside an object
# which can find a path, using inventory, to a toplavel
# object that is on a Map. 
# 
# exemple, to make an "push" starting at Morning and ending after Noon:
# 
# arch event_time
# title Python
# slaying /python/tod/push_one_period.py
# name 69,Morning,Noon
# end
# parameters are separated by comas. First one
# is connected value to trigger, other ones are
# one or more periods where state must become "pushed"
