|If the column is a DATETIME, then the statement "it is saving as MM/DD/YYYY format" is untrue.
If the output of
SELECT thedate FROM table shows different formats when executed on different systems, it is because of the "Region and Language" settings of the systems -- see the control panel -- and this is correct behaviour. If you want to override this behaviour (you shouldn't) then format it via the query.
And I strongly reccommend ISO 8601 format YYYY-MM-DD.
