It seems the datetime-local field type has a bug where if the seconds end in :00, when you click into the field and it shows the calendar popup it defaults to Dec 2000 w/ Jan 1 2001 selected. If you use any seconds beyond :00, it works fine.

JSFiddle attached, example uses `<input type="datetime-local" value="2017-05-12T19:30:00" step="1">` to show the error.
