On some, or many machines, the hardware clock (time of day) is sustained 
by a "coin cell" battery when power is off!  Sooner or later this 
battery must be replaced.  The ones I've encountered used a "CR-2013" 
coin cell.  If investigation reveals that there is such a cell it will 
need to be replaced every few years.  Observe the markings
on the old battery and find a battery to match it.  If power is seldom 
off and is restored quickly this battery may last for three to six 
years! YMMV!!!!

As I recall,the last time I needed such a battery, I purchased it for a 
dollar or two at a nearby drug store.

If this does not resolve your problem, seek professional help!
