Why 58.5 seconds?
- doublesocket 4y agoBecause then any slow clocks have 1.5 seconds to receive additional pulses from the master clock to bring them into sync.
- jonsen 4y agoThere are no additional pulses. Only minute pulses. It's a motor driving the second hand. The motor starts by the minute pulse and stops itself when reaching the top.
- dheera 4y agoTo deal with any inconsistencies in the speed at which they complete the 58.5 seconds. If a particular defective clock takes 59.9 seconds instead of 58.5 it'll be just fine, as it will start going again when it gets the next minute pulse from the central system.
