good article! I have been using their Option 3: Store what the clock should say on the wall at either the physical location or the organizers desk if it is a call. Then store the timezone string for that location and calc the UTC from that to give local start times for other users. Some apps store that UTC in the row and get re-calc’d as needed. With other apps we create views or materialized views and update rows for UTC to give a single source for sorting, etc. Storing the rules version is an improvement I will look into!
