Current time shown in some feed page hover over info boxes

[pb66]

Not sure if this is because that feed has not yet been used (no data) or because it's not a PHPFINA therefore doesn't have a proper start time meta field, either way the start time of the selected feed is not now so the current time is not the right thing to display.
