Interpretation help needed of log entry

Hi,
I have the following two entries in my log file. The first should be denied
access to, and indeed on my machine if I try to go there I get redirected to
our warning page, yet this entry would seem to indicate it was fetched?
Secondly I would like to read the time from the logs, is it in these entries and
if so how do I decipher it, if not what is the switch in the conf file to record
the time?
