[fetchmail] how do I timestamp local logfile?

I set up fetchmail to grab mail for one of my users and I set the 
logfile option to log to a file in his homedir so he could easily see 
what's going on and if there are any problems.  This log has no 
timestamps at all and I was wondering if there is a way to get fetchmail 
to put the date/time or at LEAST the time into the file?  Logging to 
syslog obviously works fine and does get time/date stamps, but then the 
user can't read the log file.  I'd like to get his local logfile 
timestamped.
Thanks,
Dave
