SQL Server 2012 Time(7) DataType values Comparison giving wrong result. Please help

Question

We have a Table with StartTime and EndTime columns in Time(7) datatype, so we want to count the rows for each hour from 6 AM to 5 AM. If a record in table is as StartTime= 7 PM to EndTime = 5 AM (a shift of an employee) then the result is wrong beacause
being time(7) datatype the EndTime(5AM)< StartTime(7PM) in 24 hours format so following query gives wrong results.
select
* from EmpSchedule
where (StartTime>='19:00:00.0000000'
OR EndTime>='19:00:00.0000000')
Please help me out. Thanks

DECLARE @clockIns TABLE (employeeID INT, startDateTime DATETIME, endDateTime DATETIME)
INSERT INTO @clockIns (employeeID, startDateTime, endDateTime)
VALUES
(1, '2014-07-01 19:01:00.000', '2014-07-02 04:27:00.000'),
(2, '2014-07-01 18:01:00.000', '2014-07-02 05:27:00.000'),
(3, '2014-07-01 19:01:00.000', '2014-07-02 05:27:00.000'),
(4, '2014-07-01 18:01:00.000', '2014-07-02 04:27:00.000')
SELECT *
FROM @clockIns
WHERE datepart(HOUR,startDateTime) BETWEEN 19 AND 23
OR datepart(HOUR,startDateTime) BETWEEN 0 AND 4
OR datepart(HOUR,endDateTime) BETWEEN 19 AND 23
OR datepart(HOUR,endDateTime) BETWEEN 0 AND 4
Try this out.
