Or you could just have your own atomic clock. It is not uncommon, and not complicated as you might think[1]. Other methods for obtaining times are: - GPS: Satellite receiver for the Global Positioning System - GNS: Combined GPS/GLONASS/Galileo/BeiDou satellite receiver (L1 frequency band), can also be used for mobile applications - GNS-UC: GPS and Galileo Satellite Receiver with Up Converter for Meinberg GPS Antenna/Converter - PZF: DCF77 correlation receiver for middle europe - MSF: Long wave receiver for Great Britain - WWVB: Long wave receiver for the US time signal - TCR: Time code receiver for IRIG A/B, AFNOR or IEEE1344 codes - MRS: (GPS, PPS, 10MHz, NTP): Multi Reference Source - several reference source [1]: https://www.muquans.com/ https://www.muquans.com/
