Why not use somthing like this: http://www.adafruit.com/products/255 ChronoDot - Ultra-precise Real Time Clock - v2.1 The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC (TCXO). It includes a CR2016 battery (not shown, but included in the product) which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required. -- Steve Kostecke <[email protected]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
