How do I convert a local meeting time between zones?

Enter the date and wall-clock time, select the source timezone and destination timezone, then inspect both the date and time in the result.

Why does a daylight-saving transition time fail?

Some local times do not exist when clocks move forward. Select a valid time and check ambiguous repeated hours separately when clocks move backward.
