PostgreSQL compare a timestamp with timezone with a timestamp

How do you compare a timestamp with a timezone with a timestamp in postgresql?
I am trying to cast one of the 2 to the type of the other but it does not work for me. Eg.



Having



TS1: 2019-01-07 21:43:00


and



TS2: 2019-01-07 20:43:37+01


I need to compare them and check if they are the same not including the seconds. So I have tried with:



select attimestamp, attimestamp_tz, attimestam=attimestamp_tz::timestamp from attendance where atid=1070


but this will always return false.
