RFC-1 Advanced Operation page 6.14
The clock gains time when it runs too fast. Suppose the clock is set to a known accurate time. Six days later at 6:00
pm the RFC-1 clock is checked. Instead of 6:00 pm it reads 6:01 pm. It is running too fast and has gained 1 minute.
Positive numbers in the table below make the clock run slower. The drift is (1 * 60) / 6 = 10 seconds/day.
Using the first example above, find -20 seconds in the table. V1=8 and V2=3. Program the value 8 at address 1018
and the value 3 at address 1019 to make the appropriate calibration.
Using the second example above, find 10 seconds in the table. V1=9 and V2=4. Program the value 9 at address
1018 and the value 4 at address 1019 to make the appropriate calibration.
