Calculate the UTM Zone.

Calculates the UTM zone for any longitude. Each UTM zone is 6 deg wide, with zone 1 beginning at long. -180 deg and zone 60 ending at long. +180. We assume that the longitude being passed in is in the range -180..+180 deg.

If you have a UTM zone/easting coordinate, then you can convert this to a longitude using the tsmUTMToLatLong function.
