I did not implement those UDF's... I imagine the reason for rigorously
using UTC instead of system time is because that can introduce subtle bugs
where your servers have a different time than your client and it can be
hard to debug, etc. It would be pretty easy to add support for timezone to
those UDF's, however, either with custom constructors or with config
