NTP is used only at the startup to set the initial date and time up to the seconds level and (starting from v6.0) later during the operation to periodically verify if WR time has not drifted from the NTP time. We do not have on WR Switch a constantly running NTP daemon to synchronize WR time to NTP time. Therefore, to do it properly, you should configure WR Switch into Grandmaster mode and provide 10MHz & 1PPS from your reference clock.

### Q: We need to use 30m coaxial cable from the GPS to the WRS Grandmaster 10MHz/PPS signals and the cable will see strong temperature changes (15-35ºC).
