Time-based triggers now in Add-ons
A few weeks ago we announced in a blog post (http://goo.gl/Js3mEH
) that add-ons could start using triggers, and those of you with a keen eye may have noticed that time-based triggers were missing from the list. It took a couple of extra days to get those working right, but we're happy to announce that time-based triggers can now be used as well.
Be aware that time-based triggers in add-ons behave differently than those in regular scripts. Most notably, they can only fire at most once an hour. Take a look at our trigger documentation for the full list of caveats.
