Appendix C.6.2.

Date and Time Synchronization

The Camry system time is not set on startup but depends on an external time synch to initialize its clock. This can
be done via BACnet time synch and should be done whenever comms to the device have been down since this
could indicate a restart. Since the time values are only correct after this synch it is best for the BACnet Client to
perform a time synch before enabling trend logging.

If the device is configured to start logging by itself from restart the initial timestamps will start at Jan 1, 1970, and a
time change record will be created on time synch.

Also note that the latest Ruinet will automatically set the system time if it connects to a Camry with an uninitialized
system time.
