I have nine clocks in the house, including the one on the microwave (and excluding any on the computers). They have been arranged peculiarly such that such that every day from the moment I wake up, time starts to diverge to converge only at the point I depart home for office.
Here is how. The alarm clock by the bedside automatically synchronizes with the US atomic time and (almost) always is perfect to the last microsecond. The clock on the wall that faces my four poster is a little ahead. Another one in the bathroom that I can see through my foggy shower door is a little further ahead. The one in the wardrobe can either be ahead or behind. The one in the living room downstairs is ahead of real but behind the one in the wardrobe. Clocks on stove and microwave are precise.
Here is why. I like to snooze my alarm clock. My alarm has a 8 minute snooze. So if I need to wake up at 6:00 AM, I set my alarm to 5:30 AM. That allows me three safe snoozes and a fourth dangerous one. I like to lie in bed for a further 4-5 minutes. The clock in the bedroom (which is a little ahead), starts to bring in some sense of urgency. I really like a long hot shower. The clock in the bathroom which is even more ahead starts to drive me into panic. As I hit the wardrobe, I have lost track of time, as I do not know if I am ahead or behind. As I dash downstairs, I start gain a few minutes as the living room clock is closer to reality. By the time I heat my breakfast, I know my exact coordinates in the fourth dimension.
Whew! Games people play!
I allow for two variables. My alarm clock has a toggle to choose the time-zone. Quite frequently, when the ascending chime disturbs my REM, I tend to hit the wrong button sending myself to a different time-zone for the next day.
And the day light savings. In spring and fall, I only set 3 of the clocks to the right hour (not minute). Different 3 clocks every cycle.
Keeps me sharp :)
I like to be on time.
