Yes, the master branch supports time zones. I don’t know if we have the documentation ready for that yet, but it should be soon.
Can you tell me more about the situation where you want to use time zones? The time zone declaration is mostly on useful in a few circumstances. The first is when you do something like GROUP BY time(1d). The time zone declaration will ensure that the day starts at midnight in the correct time zone and adjusts itself when the offset switches because of daylight savings time.
Also, TZ("America/Los_Angeles") is likely the wrong syntax. Originally, I had the PR written in a way where we used double quotes. It got changed to single quotes without me changing the commit message or the PR comment.
