- The clock is set by using "clock" just like you would use "date" to set the
- regular Amiga clock. When you first build the board, the clock may gain or
- loose a few seconds a day. You can correct this by adjusting the variable
- capacitor in the clock circuit. The best way to do this requires patience.
- Note the amount of error in a known amount of time, say a day or a week.
- Make an adjustment of perhaps a quarter turn on the capacitor (remember the
- direction). Wait this amount of time again. Note the change in the error.
- Now you can correct the capacitor by the proportional amount. If the error
- is worse, the capacitor must be turned in the opposite direction from the
- first attempt. If the error is of the opposite sense, then the first
- adjustment overshot. If a quarter turn is worth a second a day, then to
- correct a second a week will require a one twentyeighth turn. Since such
- delicate adjustments are hard to make, you may need several tries. You can
- quit when the clock is sufficiently accurate for your needs. Ultimately,
- the clock can be adjusted for about one second a month error. This may be
- more trouble than you wish to take, since correcting the time is a one line
- command.
