Yep, I have both libmacspoof and libfaketime.

But if i'm reading this correctly, I just have to run the following every time 5 or 6 days:

LD_PRELOAD="/home/user/libfaketimeMT.so.1" FAKETIME="@2008-07-15 `date +%T`" navicore

This seemed to have worked, so far, I guess I will see what happens in a few days.

Thanks!!
