--- Comment #2 from Howard Hinnant <howard.hinnant at gmail dot com> --- In my date lib I just presumed 00:00:00 time of day when parsing time_points, unless the parse produced another time of day. Though I must admit that this didn't come through in the spec. So there is a little grey area here. We're going to hit the same issue for other timepoints as well: local_time, utc_time, etc.
