Time adjustment for real-time clock.
●Use the program to adjust the time
If the highest bit of the DT90058 MSB is set to 1, it
turns to the time written into the DT90054 - DT90057
by the instruction F0. After executing time
adjustment, the DT90058 is cleared. (You can not
execute instructions other than F0.)
<Example> When X0 is ON, adjust the time to 5 days
12 hours 0 minute 0 second.

●Correct the error within 30 seconds
If the lowest bit of the DT90058 MSB is set to 1, it will
increase or decrease and turn to 0 second.
After performing the correction, the DT90058 is
cleared.
<Example> When X0 is ON, correct it to 0 second.

DF
Decrease when the execution time is 0-29 seconds,
increase when it is 30-59 seconds. In the above
example, if the time is 5 minutes and 29 seconds, it
turns to 5 minutes 0 seconds. If the time is 5 minutes
and 35 seconds, it turns to 6 minutes 0 seconds.
