Convert duration to hours:minutes:seconds (or similar) in Rails 3 or Ruby

Question

I have a feeling there is a simple/built-in way to do this but I can\'t find it.

I have a duration (in seconds) in an integer and I want to display it in a friendly form

I guess you could do also something like:

(Time.mktime(0)+3600).strftime("%H:%M:%S")

To format it as you wish.

BTW, originally I thought of using Time.at() but seems that EPOCH time on my Ubuntu is Thu Jan 01 01:00:00 +0100 1970 and not 00:00:00 hours as I expected, and therefore if I do:

Time.at(3600).strftime("%H:%M:%S")

Gives me 1 hour more than wanted.
