How do I convert 3 individuel colums with type "date", "time" and
"integer" to at timestamp with timexone?

eg. tabel
cStartUnixtime cStartTime cStartZone

This I have to present as an timestamp with timezone.

Thanks in advance

You can add the date and time to get a timestamp and then use AT TIME ZONE
with the second argument being the integer times an interval of 1 hour.
Sort of like the following:
bruno=> select ('2004-9-24'::date + '10:27:12'::time) at time zone (-2 * '1 hour'::interval);
timezone
