Calculate the approximate UTC timezone of a location.

This function splits the earth into 15 degree longitude chunks to approximate the timezone without requiring any information other than the location. Due to the vagaries of actual time-zones, the true timezone offset may differ from this value by up to 3 hours (Western China).

longitude

Longitude (scaled by 1e7)

Returns

int8_t Approximate timezone offset in hours
