sorting date column only sorts by day and ignores month and year

[pipedevnull]

I've loaded editablegrid-mysql-example recently and it is working (unmodified). However, the date column is being sorted by day of the month only and not the full date. In other words, sorting in descending order would display all dates starting with 31 then 30...29...28..etc. regardless of month or year. The other examples from webismymind/editablegrid appear to sort the date column correctly. Does anyone else have this issue or know how to fix it?

I'm confirming the issue, have the same problem here. Haven't got time to look through the codes and find a way to fix it though.
