Problem comparing dates

I amtrying to select rows that fit a certain time period.

My table:
BCV_START DATE

COL1         VARCAHR2
COL2         VARCAHR2

My data is inserted as follows:

INSERT INTO MYTABLE VALUES ( to_date('2005-07-20 16:30:00', 'YYYY-MM-DD HH24:MI:SS', 'data', 'data')

The following query is not behaving as expected:

SELECT * FROM MYTABLE where to_date(bcv_start, 'DD-MON-YYYY HH24:MI') > to_date('20-JUL-2005 01:00', 'DD-MON-YYYY HH24:MI') AND to_date(bcv_start, 'DD-MON-YYYY HH24:MI') < to_date('20-JUL-2005 17:00', 'DD-MON-YYYY HH24:MI') What am I doing wrong here?

Thx,
