Pulling my hair out a bit here, if you have 2 items in a collection created on the same day, they don't seem to change order whether you use sort="date:asc" or sort="date:desc". If I save them in the control panel with a time by clicking the timepicker, the name of the .md file has the time in it, but they disappear from the {{ collection }} loop. I don't feel it should be this difficult to order by date created so not sure what I'm missing here?
