assert(DateTime(Date(2010, 7, 4), TimeOfDay(7, 6, 12)).toSimpleString() == "2010-Jul-04 07:06:12"); assert(DateTime(Date(1998, 12, 25), TimeOfDay(2, 15, 0)).toSimpleString() == "1998-Dec-25 02:15:00"); assert(DateTime(Date(0, 1, 5), TimeOfDay(23, 9, 59)).toSimpleString() == "0000-Jan-05 23:09:59"); assert(DateTime(Date(-4, 1, 5), TimeOfDay(0, 0, 2)).toSimpleString() == "-0004-Jan-05 00:00:02");
