You seem to be slightly confused. "checkout" is for the first time and
"update" after the "checkout". About "-D ...", at least the second
one is right. I have not tried the first "-D 20030627-UTC" format.
Anyway, you can check it by "cat /usr/src/CVS/Tag".

You don't need to check out from scratch. -D "anytime" is what you need.
So in your case, 

	cvs update -dP -D "2003-06-27 00:00 UTC"

under /usr/src. "man cvs" for more details.

Seemingly you are doing right. As you pointed out, releng.netbsd.org
implies that you can build from the source of this date.
But why don't you specify another date?
