Constructor Details

#initialize(args = 0) ⇒ Duration

Initialize a duration. ‘args’ can be a hash or anything else. If a hash is passed, it will be scanned for a key=>value pair of time units such as those listed in the Duration::UNITS array or Duration::MULTIPLES hash.

If anything else except a hash is passed, #to_i is invoked on that object and expects that it return the number of seconds desired for the duration.
