Motorola SB5100 Question

I have been looking at my SB5100 Configuration and Status settings. Everything seems to be working fine, but when I looked at the Log section, all the dates are 01-01-1970, and there is a not at the bottom that reads "Log has reached it's maximum size, older data was lost". I didn't find anywhere to clear the log. Also in the status page, it tells me that "Establish Time of Day" is Done. I suppose that is set by my cable provider, (Adelphia). Are they responsible for the incorrect date/time on my Log. The times of the log entries are not in sequential order, so that leads me to believe that there may be entries from several days included. Most of the entries are near to 00:xx hours, which may be occuring at power up and shortly thereafter. That makes me wonder if Adelphia it setting the date/time to 01-01-1970/00:00 each time I power up and connect. I always power down everything at night, then power up each morning. Neither down/up time is anywhere near 00:00. Could anyone shed any light on this? Thanks.
