There is a comment in the EmuTOS sources that reads like this:

        /*
         * The IKBD clock powers up with zeros in the month & day
         * fields.  If we find that, we initialize it to the default
         * date/time, just like Atari TOS does.
         */

==> Maybe you've got to set month and day to the current date, too?
