This is a script created for the Industrial Automation Card RTC usage. The script checks if the raspberry clock is synchronized with the network time, if yes it set the card RTC, if not reads the RTC and set the system clock with it.
$ sudo /home/pi/megaind-rpi/rtc/set_time.shThe actual PATH might be different depending on your megaind-rpi PATH
The script can be run manually to check and fix the system time or can be run from cron at a few minutes intervals.
