Leap Second's effect on PASSCAL RT-130 and Q330

Summary:

Q330:

Data time starting at 2017:001:00:00:00 is +1 second from truth for 1-2 minutes (seen in controlled tests) until a clock correction, followed by a gap of 2-40 seconds per channel depending on sample rate.

RT-130:

Data time starting at 2017:001:00:00:00 is +1 second from truth for 15min - 9:42hrs (seen in controlled tests) until a clock correction. Some data (~6secs in tests) around the time correction is mistimed, sometimes 11 years in the future, or missing.

Interpreting an RT130 Log

RT130 log files are most easily viewed and interpreted with the program LOGPEEK. LOGPEEK is part of the PASSOFT software package.     This figure shows how LOGPEEK looks under normal operation. For more help or detail please see the Help section within LOGPEEK.
