If we’re including time dilation in this, so does velocity. This means that the velocity from earth’s rotation that you gain with elevation counteracts the loss in gravity to some extent (I don’t know what the total is, I can’t be fucked doing the maths). It also means that latitude effects time dilation because the equator is moving faster. This means that 60 seconds in south Africa is not exactly the same as a minute at the equator.
