Time part of a DateTime Field in SQL

Question

How would I be able to extract the time part of a DateTime field in SQL? For my project I have to return data that has a timestamp of 5pm of a DateTime field no matter what

Answer 1

This should strip away the date part:

select convert(datetime,convert(float, getdate()) - convert(int,getdate())), getdate()

and return a datetime with a default date of 1900-01-01.
