Following demos shows how to get some of the commonly required Time Part format from a DateTime.

Demo 1: Time in the 24-hour format hh:mi:ss

RESULT:

Demo 2: Time in the 24-hour format hh:mi:ss:mmm

SELECT GETDATE() 'Today',
	CONVERT(VARCHAR(12),GETDATE(),114) 'hh:mi:ss:mmm'

RESULT:

Demo 3: Time in the 12-hour format hh:mi:ss:mmmAM (or PM)

SELECT  GETDATE() 'Today',
 RIGHT(CONVERT(VARCHAR(26), GETDATE(), 109),14) 'hh:mi:ss:mmmAM (or PM)'

RESULT:

Demo 4: Time in the 12-hour format hh:miAM (or PM)

SELECT LTRIM(RIGHT(CONVERT(VARCHAR(20), GETDATE(), 100), 7))

Demo 5: Time in the 24-hour format hh:miAM (or PM)

SELECT  GETDATE() 'Today',
	CONVERT(VARCHAR(5), GETDATE(), 108) + 
	(CASE WHEN DATEPART(HOUR, GETDATE()) > 12 THEN 'PM'
