.SYNOPSIS
Adds or subtracts time spans entered in the format 'hours:minutes:seconds'
.DESCRIPTION
Time Calculator adds or subtracts time spans entered in the format of 'hours:minutes:seconds' or 'hours.minutes.seconds.'
 
By default, Time Calculator will produce output as '1 hr 25 mins 35 seconds. Toggling Traditional Format in the View menu will cause output to be converted to 01:25:35.
 
Time Calculator shows output in hours, minutes, and seconds. Toggling Show Days in the View menu will cause output to be changed to days, hours, minutes, and seconds.
 
Selecting Calculate Average from the View Menu will cause the entered times to be calculated as an average.
