Обсуждение: Data Types

Hello.

I have a table in which I'm trying to store the length of a sound file. I
decided to use the TIME data type. Was this correct? One of the operations I
want to do is sum() all of my files lengths to get the total amount in terms of
time, of sound that I have.

I notice that sum() doesn't take a TIME argument, so I cast it to an interval
as such: SELECT SUM( length::interval ) FROM songs;

However this gives me output that I don't know how to read: '7 02:34:27'
Does that read as 7 Days, 2 Hours, 34 Minutes and 27 seconds?

TIA
