> Even something as simple as a Chronodot will hold to a few seconds a year.
Eric, Are you sure? My understanding is that the Chronodot is based on the DS3231. Quoting http://datasheets.maxim-ic.com/en/ds/DS3231.pdf we read: The DS3231 is a serial RTC driven by a temperature compensated 32kHz crystal oscillator. The TCXO provides a stable and accurate reference clock, and maintains the RTC to within ±2 minutes per year accuracy from -40°C to +85°C. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
