Hi,

I am subtracting 2 times which gives me the time difference in seconds
as a float.

How to I convert something like 3.815824 into 0:03 minutes?

Thanks in advance!

Cheers,
Chris.

Hi Chris,

into 0:03 minutes?

There’s nothing I know of ‘in the can’ for that level of granularity,
but
take a look at the source for distance_of_time_in_words helper (at
api.rubyonrails.org). That should put you on the right track.

Hi Kevin,

require ‘ruby-units’

a = time1
b = time2
c = (time1 -time2).unit(‘min’)
c.to_s(’%H:%M") #=> ‘00:03’

That’s cool. Where is ruby-units documented?

Thanks,
Bill

require ‘rubygems’
require ‘ruby-units’

a = time1
b = time2
c = (time1 -time2).unit(‘min’)
c.to_s('%H:%M") #=> ‘00:03’

This works well if you need to do math on the units, or if you have to
deal with a wide variety of units.
