Compare two cities' local times and find which is ahead.
The absolute difference between the two UTC offsets is the time gap, and adding the signed offset into City A's current hour yields the live time in City B. This makes the direction and size of the gap clear. A visible time gap between two cities prevents misreading a business call or tour time at the destination.
Travel Time Difference
Difference = |B offset - A offset|; B time = A hour + (B offset - A offset)
Difference = |B offset - A offset|; B time = A hour + (B offset - A offset) The absolute difference between the two UTC offsets is the time gap, and adding the signed offset into City A's current hour yields the live time in City B. This makes the direction and size of the gap clear.
