Probably related to this * fetchmail, with --logfile, now logs time stamps
into the file, in localtime
   and in the format "Jun 20 23:45:01 fetchmail: ". It will be localized
through
   the environment variables LC_TIME (or LC_ALL) and TZ.

I think it is for the benefit of IMAP IDLE.
In that mode fetchmail keeps an open connection to the server
and logs whenever the server offers/pushes a new messages.

IMAP IDLE saves fetchmail from starting a new connection (including 
setting up encryption) every few minutes and allows it to be completely
idle until there is a new message.
It doesn't support more than one remote mailbox
(unless you set up separate fetchmail processes with separate configs).
