Time zones can be quite complicated and are common source of misunderstanding when having to plan a meeting when traveling (it happened to a friend and I recently).
- In some places there are summer vs winter times while not in other places.
- Time shift to adjust to another season may occur at different dates at different locations
- Lots of such variation can exist within a single country.
- It may happen that two communities at the same location uses different time zone.
- Some time zone are shifted by 30 minutes only
To get an appreciation of the complexity of time zones, I invite you to have a look at this computerphile video.
Can you give me recommendations of websites that allow one to set a time and date at a given location (and community when different communities at the same location use different time zones) and get the corresponding time and date at another arbitrary location?
