Grepping the last 30 minutes of a log file...

I need to know if anyone can assist me on how to grab the last (we'll just say "x" minutes) of a log file. How do you tell the grep command without specifying an exact window of time? (So relative instead of absolute.)

Thanks,

Jon

How is the timestamp specified in your logfile?

The actual entry looks just like this:

03-05-2008 23:24:32 blah blah blah

Thanks in advance.
