What is Set Clock?

Two handy tools can help you keep track of time. The first is Jim Leitch's Set Clock. It sets the Mac's clock to with in one-second accuracy — The clocks in the Mac are silicon-chip-based; some of them are clunkers that lose or gain a second or two per week. Set Clock keeps all Mac clocks equal and accurate.

Set Clock works by placing a ten-second telephone call to Leich Video's master clock driver, which constantly synchronizes itself (to within one-millisecond accuracy) with an identical unit maintained by the Canadian government that is referenced to an atomic standard. In other words, it's very exact. You need a modem (300 bps will do) that can deal with a basic Hayes command set. The phone numbers are provided primarily for Leitch Video customers whose equipment must he precisely calibrated, but Set Clock gives you access to them at no cost beyond the tariff for the phone calls (about 20¢, if you call at night).
