how to log date/time in daemon mode?

Greetings, long time fetchmail user here;

I was subjected to a phishing attack yesterday and again today, and it 
would have been a lot easier to correlate the messages if fetchmail was 
logging the time, preferably the date/time at the end of fetching of 
fetching each mail. Something it is not now, and never has done.  And I 
just reread the man pages without finding a clue.

How do I enable this so a date/time exists in the fetchmail.log?
