• The RJ71CN91 does not support daylight saving time.
• The actual clock time data will be delayed by the time required for internal processing of the RJ71CN91 and
data communication processing in the network.
• Leap years are automatically adjusted.

*1 A TIME message will be produced only if the RJ71CN91 is the active NMT master.
*2 If the RJ71CN91 is a TIME consumer, this value is disabled.
*3 If an NMT reset occurs, the set values of the object dictionary that have not been saved yet are written over by their initial values. For
this reason, operation different from the operation before an NMT reset occurred may be performed. If the set values of the object
dictionary are written over by different values, create a program for writing the set values again and re-configuring the object directory
with 'Time stamp setting request' (Y12).
Program example (When 2 (Producer) is set in 'Time stamp' (Un\G50.0) with the start I/O number of the RJ71CN91 at 0)
