Date/Time Range

It seems that every time I implement a class in Ruby I later find out
someone has already done a much better job than myself.

So before I take the time to implement a TimeRange class myself, I
thought
I’d ask if there was anything out there similar.

I’d like to be able to do something like the following:

start_date = Time.parse “9/1/2006”
end_date = Time.parse “9/2/2006”

r = TimeRange.new(start_date, end_date)

r.each_hour do |hour|

end

r.each_day do |day|

end

r.each(1800) do |half_hour|

end

Any suggestions are welcome.

Thanks,
Michael G.

Hmmm… strange that you should ask.

a = Time.now

(Unit(‘0 h’)…Unit(‘10 h’)).map {|hour|a + hour}

To do this, you need to use the ‘ruby-units-0.2.1’ gem.
I’m putting a few finishing touches on it, but it should be available
later tonight. There are also a bunch of handy time helper functions as
well.

PS. Works with seconds, minutes, hours, days, weeks, fortnights, years,
etc…
The range version requires that the interval be integers, so you would
have to use another looping structure for 15-min or 30-min intervals.

Perfect! This should do exactly what I was looking for.

Thanks!
