Subject: 2/24 = 0?; or, how do I add hours to a DateTime?

Hey All,

I'd like to run some code repeatedly, for 2 hours and then stop.  I
figured I'd do this:

start_time = DateTime.now
two_hours = 2/24  # <--- This evaluates to 0?

finish_time = start_time + two_hours

until DateTime.now >= finish_time
   # do some stuff
end

But it seems that 2 divided by 24 (which is what I intend by '2/24') is
evaluating to zero, so my code never runs.  What am I missing?

BTW--I was disappointed not to find an add_hours() method on DateTime.
Did I just miss it, or is it really not there?

Thanks!
