Ruby: Convert time to seconds?

Question

How can I convert a time like 10:30 to seconds? Is there some sort of built in Ruby function to handle that?

Basically trying to figure out the number of seconds fro

Answer 1

require 'time'

def seconds_since_midnight(time)
  Time.parse(time).hour * 3600 + Time.parse(time).min * 60 + Time.parse(time).sec
end

puts seconds_since_midnight("18:46")

All great answers, this is what I ended up using.
