# 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.py
# msg
# {
# "connected":"69",
# "when":["Morning","Noon"],
# "match":"one"
# }
# endmsg
# 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"
