Real Time Clock

I have used RTC function block from Standard/TimerEnh library.
But for me it works in a very strange way.
Time on the output is time on the input + offset time since first use of RTC.
Is there any method to obtain real RTC? I mean system time.

Since this seems to be a logi.CAD3 question I have moved your post here. So I hope that the experts from logi.cals will provide help for your questions. Maybe this discussion here is involved as you have to synchronize the RTC with the system time.

Ingo, thanks a lot for your link, this github code works like a charm and is very easy to use in logiCAD3.
