Convert 12 hr time to 24 hr format in Ruby

Question

How do I convert \"11am\" and \"10pm\" into \"11:00\" and \"22:00\"? Is there a simple way using the date and time classes?

Answer 1

The Time class has no parse method, but DateTime has.

require 'date'
DateTime.parse("11pm").strftime("%H:%M") #=> "23:00"
