We do have a user override for timezone, and we're using it to track how many mistakes we're getting from the browser - we were expecting it to be pretty hit & miss, but we've actually seen great success.

Good thought about being able to change when morning emails fire. The 7am is really a relic from when we first started, even before we had the rolling timezones - we were trying to hit a time that worked for west coasters & east coasters alike, and sure enough, we got a ton of overseas users way sooner than we thought, so out came the rolling timezones. :)
