Description

The TcNtpExternalTimeProvider is configured under System > TcCOMObjects.

Here you can parameterize your own NTP server under Parameter (Init), if the default pool.ntp.org cannot be reached.

The C++ module cyclically determines a local timestamp in the CycleUpdate() method and corrects it. It can be traced in the respective steps using the debugger. The corrected timestamp is provided as a parameter (online).

The type required for this can be configured as parameter "TimeType" in the TcCOM object.
