/*
This macro converts a timestamp column from Unix epoch time (in milliseconds) 
to a UTC timestamp and a corresponding UTC date.

It generates two output fields:
1. The timestamp in UTC, with the alias formatted as <column_name>_at_utc.
2. The date in UTC, with the alias formatted as <column_name>_date_utc.

This macro is intended to be used within a SELECT statement 
and ensures that the output is properly formatted for further analysis.
