For questions about the standard passage of time on objects/people/civilisations etc. Also consider the [time-keeping], [spacetime-dimensions], [alternate-history], [universe], [time-travel], or [time-manipulation] tags.
This tag is for questions about the effects of standard passage of time on objects/persons/civilizations etc. Questions should be based on the realistic concept of time, rather than more fictionalised concepts.
Also consider the following time-related tags:

- spacetime-dimensions, if space is involved - typically as the result of relativistic effects.
For questions relating to alternate-time and the multiverse consider using the following tags:
- alternate-history, for timelines involving a different sequence of events.
- universe, for alternate/parallel universes and the multiverse.
For questions relating to more fantastical ideas consider:
