title: What happens to installable time-driver triggers when a Google Sheets document closes?
body: <p>Seeing as a simple time-driven script runs whether the Sheet is open or not, I now have installable time-driven functions instantiated when the onOpen function is evaluated. My question is: what happens when the document is closed? Do the time-driven functions continue to execute? If so, is there a way to tell them not to do unless the document is open?</p>
