Name: Second Time Zone - Dual Clock Field
Author: RiversideArt

Second Time Zone shows the time in one other zone next to your activity data. Pick the standard offset from UTC in settings, including the half and quarter hour zones, and turn on summer time for that zone when it applies.

The field computes the time from UTC and the offset you choose; it does not look up a city or know when a zone changes its clocks, so check the summer time switch when the season changes.

Add it to a data screen of your activity like any other field.
