--[[ Sample usage.
  local dtFormat = '!%m/%d/%Y %H:%M:%S';
  DeleteAndReCreateTimeTrigger('TwitterNews','TweetReceivedTime'); --just recreate it so it gets no fired flag use existing time.
  DeleteAndReCreateTimeTrigger('TwitterNews','TweetReceivedTime',os.date(dtFormat,1748248200)); --normal method.feed it string time.
  DeleteAndReCreateTimeTrigger('TwitterNews','TweetReceivedTime',1748248200); --feed it std unix time and will convert to .net for you.
  --Get the existing time but add 5 minutes too it when re-creating.
  local e = ScenEdit_GetEvent('TwitterNews')
  DeleteAndReCreateTimeTrigger('TwitterNews','TweetReceivedTime',convertDotNetTickTimeToLuaTimestamp(tonumber(e.triggers[1].Time.Time) + 300))

Can be helpful with you have a dozen times you need to reset to known times for whatever reason or just need to 
reset the fired flags. Write a reset helper function that just makes a call for each one and evertime you need to reset
you just run that one function. This assumes you're not tracking specific trigger-id guids (since they change on recreation)
though Imagine those cases are few and far between particularly for time-triggers.
