12.2.5. Time adjustment
This function permits the system to receive time correction signal from a master or wave clock to correct the
system's time in ±30 seconds units.
The time correction is performed by the timing of a pulse rising edge.
Time is corrected as follows:
• When time is from 0 to 29 seconds, it is corrected to 0 second.
(Example) When the SX-2000SM's time is 07:15:15, it is corrected to 07:15:00.
• When time is from 30 to 59 seconds, it is corrected to +1 minute, 0 second.
(Example) When the SX-2000SM's time is 07:15:45, it is corrected to 07:16:00.
