1730 Series
The 1730 series loggers do not have an external time sync option. The time and date are manually programmed in the settings. If it is not programmed, time comes from the ARM processor which stores periodic time and date (in case the value is lost due to very low or dead battery).
You can find instructions on how to set up the time and date in the user manuals (1732/1734 manual, 1736/1738 manual).
1740 Series
1740 series loggers can sync to NTP. Access to the time server on the network is required. See the user manual for setup instructions.
You can also use GPS satellite time. The GPS accessory is required.
