Geoff,

Actually the log file does show the time and date of the request being made:
1                                             2 
3                                                   4 
5             6    7
www.cryptodan.net static-173-73-4-106.washdc.fios.verizon.net - - 
[18/Feb/2010:20:08:04 +0000] "GET /forums/Themes/default/TPShout.css.css?fin11 
HTTP/1.1" 404 258

1 - Domain Accessed
2 - Remote IP making the request
3 - Time and Date of the request based on the system time and date (should 
always be set to GMT/UTC) to make issues easier to troubleshoot.
4 - Content
5 - HTTP Protocol Version used
6 - HTTP Status Code
7 - Size of request

You can use simple programs to search for information you want in the log files. 
You could also install and configure webalizer to easily group like IP Addresses 
to better troubleshoot your issues.

Thanks,
Dan
