SmartScan can synchronise to a NTP time signal via its Ethernet port.
In this scenario SmartScan would need to be connected on a Local Area Network (LAN) and would also need to be able to access an NTP server, either on the same LAN or over the Internet.
All the data from SmartScan is time stamped, so if an NTP signal is received the timestamps would be synchronised to that signal. See “Plug-in for NTP synchronisation” in the SmartSoft user manual.
