Which part do you not understand - I'll try to help.

The suggestion - a timer that runs for every minute you do not play.

The good person - Plays every day, usually the same time, take for example 7pm to 8pm and playes all their games.

The bad person - knows this persons schedule, waits until 8:01 after they sign out and plays their game.

Timer starts to run on "good player" - 23 hours taken from clock. Good player makes his daily move at 7pm the next day.

Bad player - Waits until 8:01 until the good player signs out and plays the game again. Bad player only had 1 hour taken off the time.

Yet again, the good player is off for anouther 23 hours (making the total of 46 hours off the main clock)

(Well keep doing this example for awhile, and the time will add up quickly - and if there is a limit of lets say 50 total hours, well after 2 1/2 days, the game would end.)

A suggestion I made to hopefully make it so the good person to not time out is to have a 24 hour grace period before the timer starts to run.

Does that help.
