The clock settings should be set to Auto so that the clock is set by the broadcasted signal; this will automatically update when the clocks change.

Note that Recording start and end times should be set to On Time to ensure that the broadcaster's start and end signals are used. If either of these are changed, the timing becomes manual, and functions such as Series Record are not available.

Clock logic can not be changed replace the whole board
just lets you change the time will not let you slow it or speed up

If If you mean the time clock, just keep pushing the little indentations below the clock with a pin to change the hour and then the minutes :-) If you mean the speedo clock, no can do, reads mileage from ECU and gearbox to prevent tampering with mileage.

My understanding is this timer uses typical T100 series 120Volt clock motor.
The motor has identifying numbers printed on it.
T100 series 120V clock motor is available at Grainger:

Selection of Intermatic clock motors are available on-line:

To replace motor:
Timer mechanism snaps out of box using a thumb-spring located at top of mechanism.
Clock is located on back of mechanism, and is held by 2 star-screws.
You can buy star screwdriver bit at auto parts store or hardware.
Clock motor has two white wires that are connected to terminals on front of timer.
Be sure to tighten terminals screws very tight after replacing clock motor.

this post is for projectors, not clocks. sorry.

hi..

put your keys in so that your instrument clsuter on the dash come on,(no need to start the engine), use your mileage reset button to change time by turning it clockwise and anticlockwise till you reach the correct time.. it will change on your dash aswell as your radio..
