I just wired up an Intermatic T103 timer. I noticed after 12 hours
the timer seems to be moving to fast (12 hours registered about 13
hours on the timer). Could I have a wiring issue or is this just a
faulty clock timer? TIA.


Probably a faulty timer, but check to see if it has an automatic DST switch
that happened to trip if it is one hour even.
