Dattime format problems when retrieved on FreeBSD server

I'm using MSSQL with PHP and this works fine on a Windows server.

When i move to a FreeBSD server, the date formatting is not working.

FreeBSD retrieves the date as: mon dd yyyy hh:mi:ss:mmmAM - and php's functions for formatting date fails.

I've tried using: Convert(varchar(10), Date, 103) AS Date, and the date is formatted fine - BUT sorting on date does NOT work.

Are there any way i can do changes to datetime behaviour on server side? I NEVER wants the date in mon dd yyyy hh:mi:ss:mmmAM. I don't need milliseconds, and i want 24h format - not AM/PM. Are there any settings on the SQL server for this?
