int(11) is outputted as a date

Hey guys,

I'm new to this forum and it has been some time since I was working with DB's.

Here is my problem. I have a table with a column called "inside_date". This column is of type "int(11)". In it I have a number, e.g. 1327939700. The output on the website is then "Monday, 30.01.2012".

I do not have a clue on how this number is transfered into this date. Can some one please give me an explanation?!?

What would be the number for "Wednesday, 08.08.2012"?

THANKS for your help. :)
