Not without scheduled jobs (crons or the equivalent) or always-live processes, no. If you're leaning on a runtime the server owns and your own code is never invoked, you are (or your account is) not using any CPU time.

The system in Oz at least used to be similar. Which is great if you're actually posted to a vessel. That isn't always the case in Canada; we air types, the folks what flies and fixes the helicopters, are nominally "Air Force" and are seconded to ships for voyages only, remaining on squadron strength back at our home airfield, so unless one is vigilant about changing addresses every few weeks, important mail may be headed to your post box at the barracks while you're at see and to the ship while you're at home.
