SQL Developer is returning only the date, not the time. How do I fix this?

Here’s what SQL Develoepr is giving me, both in the results window and when I export:

CREATION_TIME       
------------------- 
27-SEP-12
27-SEP-12
27-SEP-12

Here’s what another piece of software running the same query/db gives:

CREATION_TIME       
------------------- 
2012-09-27 14:44:46 
2012-09-27 14:44:27 
2012-09-27 14:43:53 

How do I get SQL Developer to return the time too?
