Post published at the wrong date

2016-10-03-datashader-mola.md was named correctly wrt the desired publishing date, but was actually published before, for unknown reasons.

Really strange , locally I cannot reproduce it. If I set the right date in the filename it is used, if no "date :" is defined in the file header/ If i set "date :" in the file, it overwrites the filename.
