I got it to work however there is a little problem with the “hours arm”
As you can see it’s displaying the system time correctly (red = seconds, orange = minutes, green = hours)
and this is the BP for it
But it needs some more work because for example at 13:30 the hours arm will be staying on exactly 13 (the others will be in place) so basically the hours arm moves only when the hours change on the system (this can be fixed by changing the rotation for hours from “System Hours * 30” to something that includes both the system hours and minutes)
