This is great!! Wasn't aware of this at all. Is the <something that does utc> part db dependent? I am only familiar with mysql, so if I change to other db in the future, and the <convert to utc> function is called 'convert_to_tz' instead of 'convert_tz', will this break? I know I can access the named tuple using the following before.
for r in rows print r.event_ts Now with the func.convert_tz(), can I use something like func.convert_tz() AS ts, so I can reference it with r.ts?
