I am in some ways a beginner also. But here is one way to calculate error.
Figure the number of seconds in 100 years. You just compute the number in a
minute (60) times the minutes in an hour (60) times the hours in a day (24) and
so on. When you get to 100 years after all the multiplications you will have
calculated the number of seconds in 100 years.
Myultiply that by the error in your time base. If the error is one part in 10
to the 12th, then you multiply by the number of seconds in 100 years and it
will give you the error, in seconds, after 100 years.

Without wanting to show my ignorance by confusing accuracy, and precision,
etc, would some kind person please answer the following : Let me explain -
I have my prototype GPS diciplined [ Trimble inside] standard frequency
source connected to both a divide by 5,2,5 and 2 producing all the
reference frequencies necessary for the various bits of equipment in my
workshop, AND the 1pps
output connected to a 7474 "T" flipflop and thence via a 100uF capacitor to
a modified $10 analogue wall clock. Can anybody tell me this : If I live
another 100 years [Let`s say I take antioxidants ;-) ] what sort of error
should I expect in this clock? [I know that it`s better than 1 second per
day]
