When I enable NTP Server time updates on my DAP-2310 it always updates to January 1, 1970. The only way I can get the time to change is by manually updating it.
I also have a DIR-655 on the same network and use NTP Server to update time and it works great.
Is this an issue with the DAP-2310? Both devices have the latest firmware as of 10/26/2013.
