Is there an existent lib or such that gives me some date/time calculations =
?

Time.now - 2.minutes for instance ?

Thanks,

Time.now - 2 * 60

or

(some people would argue that this is the best approach)

Minute = 60
Hour = Minute * 60
Day = Hour * 24
Time.now - 2 * Minute

or

The ActiveSupport library for Rails has those sorts of methods defined.

or

I think Facets might have these, too.

or

Roll your own. They are easy to write.

ActiveSupport, which is part of Rails, has this stuff. Take a look:
