> Examples where this might be useful is data syncing between two locations.
> Relying on modification times to detect data changes may lead to a feedback
> loop of copying: data gets created at location A at time 0, at time 1 data is
> copied to location B, sync mechanism might incorrectly believe that since mod
> time of location B is higher, it should be synced back to location A, etc.
