Is this a Asus Router hack?

[colthorp_cross]

I have a Asus RT-AC66U, configured as a Media Bridge. I have done a hard reset and loaded the latest Firmware. I have deleted old logs and saved settings. Very unstable and stops for no reason. Here is a typical log after rebooting. The February date is the same every time, then returns to current time.

Most likely the date of the firmware. 714361 is 496 days. Subtract those days from Jun 24 and you get Feb 14 2017.
