One time zone per person, across every SB app

Your time zone used to be a Time Tracker setting. It is now part of your SB account, so the zone you pick once is the zone Time Tracker, Project Management and CRM all show your dates and times in.

Set it on Profile as before — the card now says which zone you're seeing, where it came from, and what happens if you leave it blank. Leave it blank and you follow your company's default.

That company default has moved too: it's an account-level fact now, so it's edited once in SB Account instead of separately in each app. Settings → Company shows the current value with a link to change it. Nothing to do if you'd already chosen a zone — it came along.
