After installing the latest OSPi SD Card Image 2 I found that it handles the Real Time Clock out of the box. I tried to compare the actual configuration with the description of this RTC settings wiki page. There are some differences e.g.
– the ntp settings to use RTC as source of time if no internet connection is available
– cron script to calibrate the RTC from the system clock once a week
– cron script to adjust the RTC for drift each day
Despite of this differences the RTC was synchronized automatically and Pi gets the RTC time if there is no internet access. Can I consider that everything is fully configured in this image and RTC will work as expected including daily and weekly adjustments?
