For example when planning meeting times, the reason local time comes up is ultimately some determinant about when it's going to be day or night - that's the actual metric that meeting planning generally tries to take into account.
Strictly speaking I would say this also applies for storing data about machine to machine events which might be normally considered to be purely sequence based. If we're storing times to determine processing order for example, then there'd be value in storing the lat/lon of the machines generating them, because it's an extra datum which can resolve expected ordering (i.e. based back-calculating latency windows).
