#

HoursToSeconds[]

The following asks this question:

"How many seconds does a 24 hours day have?"

Usage example:

x = HoursToSeconds[2, :be_quiet] # => 7200

start_conversion

This is called from the method run(). It will set the ivar @n_seconds.

The method will assign to the instance variable @splitted.
