Limitations

Some important limitations have to be taken into account:

• The TwinCAT system time is not changed by the external time interface described here
• The external time offsets are made available to the consumers as provided by the provider. It follows that
• the offset must be calculated correctly by the provider.
• no monotony can be guaranteed in the timestamps.
• The external time offsets are not saved and subsequently made available for retrieval. This means that only the current offsets are managed in the TwinCAT system.
