Can someone tell me why this statement is failing?

Can anyone tell me why this SQL statement is not
matching with the row from the table below? I think
I'm going mad!

#####################################

SELECT * FROM t_bell_schedule WHERE calendar_day =
'2004-04-12' AND start_time_minutes >= '1082374200'
AND end_time_minutes <= '1082375100';
