Thanks Monteblack,
I contacted Dallas Avionics from the website you gave me and they gave me a
tech number for a Mid Continent representative. (Mid Continent's website
doesn't provide a tel number).
The technician said there is no way to adjust the MD-90 clock and they will
send me a new one and I send the other back.

I had a brand new Mid-Continent MD-90 clock installed in my Cessna 172. It
runs real slow and I would like to know is there a way to adjust the
clock?

Unplug it ....wait for 12 hours, plug it back in?


(The "good one" was already taken)
