HowTo? CURRENT_TIMESTAMP AT TIME ZONE 'UTC'

Question

How would I amend my calls to

sqlalchemy.func.current_timestamp() 

with something that generates

CURRENT_TIMESTAMP AT TIME ZONE 'UTC' 

Answer 1

A quick fix would be to do the following:

func.current_timestamp().op('AT TIME ZONE')('UTC') 

A more proper way is to use compiler extension and define custom compilation of CURRENT_TIMESTAMP. Actually, there's already an example in its docs, which uses a different approach (TIMEZONE function). Since you only need this for Postgres (I assume from your previous emails in SA mailing list that you're using Postgres), here's another (nicer) quick fix:

func.timezone('UTC', func.current_timestamp())
