I had this error in the Log of the HG612 just the one.
2000-1-1 0:0:3 Warning 10400 KLOB Pool 1 Initialized: 1048576 bytes <0x80300000 ... 0x80400000>
That usually immediately follows a reboot, so it isn't really an error.
If you did indeed set the date/time for the inbuilt log, then a reboot resets it to 2000-1-1, whereas an on the fly resync doesn't:-
