Yeah I am doing from there too.
I checked if its turkish language pack related thing, but when I change my language to English I still see "<span title="">Yesterday</span>" instead of m-d-Y order.
It looks like it's related to time changes in 1.8.12, MyAlerts was having the same issue and I had to change some codes too.
