Comment 19 for bug 48679

In my endeavors to find the source of this bug, I came across this snippet from evolution-data-server/calendar/backends/contacts/e-cal-backend-contacts.c:

static struct icaltimetype
cdate_to_icaltime (EContactDate *cdate)
{
        struct icaltimetype ret;

/*FIXME: this is a really _ugly_ (temporary) hack
 * since several functions are still depending on the epoch,
 * let entries start (earliest) at 19700101
 */
        ret.year = cdate->year >= 1970 ? cdate->year : 1970;
        ret.month = cdate->month;
        ret.day = cdate->day;
        ret.is_date = TRUE;
        ret.is_utc = FALSE;
        ret.zone = NULL;
        ret.is_daylight = FALSE;

        ret.hour = ret.minute = ret.second = 0;

        return ret;
}

The above "temporary hack" has been in there since revision 3557 in March 2004...
