Direct Answers

Why is timezone conversion still easy to get wrong?

Because the source timezone, target timezone, and daylight-saving rules all need to be correct at the same time.

Should I store business schedules in local time or UTC?

Usually store a canonical form in UTC, then convert to local time for communication and operations.
