convert(char(8), dateadd(HOUR, -6, EndTime), 112)

The dateadd() functions brings the EndTime six hours back in time. The
convert to char(8) with code 112 strips of the time portion.

You can read more about dateadd and other datetime functions in Books
Online. You can also read about convert() under the topic CAST and CONVERT.
