Programmatically created nodes are shown only after re-saving I'm creating a lot of nodes programmatically in a custom module. These nodes are showing up on admin/content and in a default view display (unformatted/fields), but not in a calendar view display. Only if I open and resave, those nodes will be shown in the calendar view.

Why is this happening? All nodes are published.
SOLVED: I was using a timestamp for the generated dates, but it needed to be a string like: "1967-01-15T00:00:00". I needed to look up the values in my database directly, devel / dpm() did not show a difference.
