Add nostradamus in Gemfile and run bundle install.

gem "nostradamus"

Or only execute gem install nostradamus on terminal.

How to use

Human time to seconds:

Nostradamus.parse("10:00") # => 36000
Nostradamus.parse("10:00:00") # => 36000

Seconds to human time:

Nostradamus.humanize(36000, :short) # => "10:00"
Nostradamus.humanize(36000) # => "10:00:00"

Sum with seconds

time = Nostradamus.new("12:00") + 60
time.to_i # => 43260
time.to_s # => "12:01:00"
time.to_s(:short) # => "12:01"

Sum with another Nostradamus instance

time = Nostradamus.new("12:00") + Nostradamus.new(60)
time.to_i # => 43260
time.to_s # => "12:01:00"
time.to_s(:short) # => "12:01"

Compare times

Nostradamus.new("12:00") == 43260
Nostradamus.new("00:01:00") == Nostradamus.new(60)

Returning a Time object

Nostradamus.new("12:00").to_time # => Returns a object: Time.new(CURRENT_YEAR, CURRENT_MONTH, CURRENT_DAY, 12, 0)
Nostradamus.new("12:00").to_time(:on => Date.new(2012, 5, 1)) # => Returns a object: Time.new(2012, 5, 1, 12, 0)
