Selecting an interval from a integer column in PostgreSQL

I needed to create a select that combined a timestamp in one column with an interval specified in minutes from another column. After much manual reading and searching I found the answer on stackoverflow. My SQL looked something like:

SELECT d.time AT TIME ZONE 'UTC' + interval '1 minute' * d.minute as time FROM my data d ...

Much faster than using Perl’s DateTime::Format::Pg and DateTime::Duration modules to do the addition.
