No, sorry - none of our products have an RTC. The playlist timing is generated when you insert the USB drive and import the history.
Does the CDJ-850 has a real time clock?
It seems like a miracle. When I insert a USB-Stick back in my rekordbox PC, the Histories of my played songs are listed there. But how does the CDJ knows, when I played them? Has it some sort of realtime clock? And if "yes" how is it set? I've found absolutely nothing.
