MRTG & Hobbit

This may not be directly Hobbit related, but...

I get the message "Time stamp in log is on the future !" on each of my
MRTG pages.  I was not getting this when running bigbrother, so I'm
wondering what would cause this or if there is something I can do to
keep that from appearing.  MRTG is working fine, just this annoying
message.

Thanks,
Michael
