I want to emphasize the followings:
- FB's RTC (real-time clock/motherboard clock) is synchronized to NTP time.
- The other RT machines are not synchronized to NTP time.
- My speculation is that the RT machine timestamp is produced from the local RT machine time because there is no IRIG-B signal provided. -> If the RTC is more than 1 sec off from the FB time, the timestamp inconsistency occurs. Then it induces "DC" error.
- For now, we have to use "date" command to match the local RTC time to the FB's time.
- So: If NTP synchronization is properly implemented for the RT machines, we will be free from this silly manual time adjustment.
