mytime.m

When called without the reset argument, mytime() displays the current date and time, time since the last invocation, and total elapsed time (since the last reset). If a given time value is less than 120 seconds, it is displayed in seconds and hundredths of seconds. If at least 2 minutes but less than 120 minutes, it is displayed in minutes and hundredths of minutes. If greater than or equal to 120 minutes, it is displayed in hours and hundredths of hours.

When called with the reset argument (the value of this argument is unimportant), the timer is reset to zero.
