Robert, following all of your advise: it works. Thanks a lot! I have installed rtc's on about 7 BBB's the last 5 years and it always was a challenge. Mainly because the procedure changed a lot. In addition, I added an rtc service and the Beagle now shows the right time even when not connected to the internet. I still feel a newbie, though. Thanks again, best regards, Harke
