Add a number to a date, you get a date that many days out. Similarly, you can add an interval to a timestamp. So you'll need to know the base used for those numbers, and the unit of measurement.

For instance, if the numbers for date are an offset from 1970-01-01 (Unix epoch):

'1970-01-01'::date + <number>

If the numbers for time are seconds from then:

'1970-01-01'::timestamptz + '<number> seconds'::interval

Of course you'll also need to know what time zone the times are in, I will graciously leave that as an exercise ;-)

Also, the documentation page you needed:
