Ok, I'm slightly confused.

Are you saying that in the query yo have somethinbg like:

        WHERE m_when between '14-Sep-2011' and ...

where you use strings as the "date" values you are looking for but that 
Sql*Plus gives no rows while SQL Developer gives lots? That's surely a 
bad thing.

Assuming your NLS_DATE_FORMAT string is something that your strinsg 
resemble, Sql*Plus should be able to implicitly TO_DATE() the strings 
and should return valid results?

If your date format is not compatible with your string format, Sql*Plus 
should throw an error, not simply return zero rows?

Equally. SQL Developer should do the same - in my opinion, either 
convert the date according to NLS_DATE_FORMAT or barf.

Just my £0.02.
