Get rid of them. Timezones are a leaky abstraction over daylight. They are to broad, so run into these failure modes. I would train people to run off of UTC time most of the time when they need to synchronize a specific time. Then train them to run off of sunrise/sunset offsets for situations where daylight matters. Most of the parks in my neighborhood are open sunrise to sunset, that's perfect. With modern digital clocks, this would be trivial to setup. When should work hours be? Either some UTC time if we're remote, or if all local, something like 10 hours before sunset to 2 hours before sunset.
