AutoClock is an application and a system extension that maintains the accuracy of your Macintosh clock. As a matter of fact, this clock has the tendency to deviate from the correct time every day, and can accumulate to minutes or dozens of minutes after one year, if not corrected.
The AutoClock application allows you to:
• set the clock by calling a time server, if you have a modem,
• set the clock manually from an accurate source (for example a voice time server (303-499-7111) or the radio),
• display a logbook of every clock change on your Macintosh, whether it was done with AutoClock, or with another application (the General or Data & Time control panels, or the Clock desk accessory for example),
• compute the mean clock deviation of the Macintosh clock for a 24-hour period, using data recorded in the logbook, and
• display the date and time in almost any country of the world.
The system extension AutoClock Extension can:
• periodically open the AutoClock application according to your schedule, to perform an automatic clock adjustment by calling the time server, without any user intervention,
• keep the Macintosh clock continually correct, by adjusting it using the computed mean clock deviation,
• automatically adjust the clock for Daylight Saving Time, and
• detect any clock changes done by any other programs, and record them in the application's logbook.
If you don't know how to use a command, or how to set an option, don't forget to read the documentation or activate help balloons in AutoClock.
Important !!!
-----------
If you are one of those who never reads documentation, read the following important recommendations:
• Keep the port speed (communication settings) to 1200 bps, even if you are using a faster modem. The rare exceptions are for modems with a locked interface speed.
• If you are using a fax or server software and AutoClock is unable to use the serial port, check the "Force Port" box (communication settings). Do not use Force Port unless you find it necessary.
• Check if the time server phone number are correct. In general, each default phone number is valid if called from the same country as the time server. You will have to add/remove an international prefix or country/state/area, depending upon your exact location.
• If the default initialization string AT&F does not work with your modem, check the documentation: I included working initialization strings for some popular modems.
The AutoClock application and AutoClock Extension work on any Macintosh, with System 6.0.5 or later, including system 7 and 7 Pro. AutoClock is 32-bit clean, and has balloon help if used with System 7.
