NetBSD fuchsia 1.5Y NetBSD 1.5Y (FUCHSIA) #2: Mon Nov 26 13:41:27 ICT 2001     kre@fuchsia:/usr/obj/sys/FUCHSIA i386

>Description:
	There is no (easy anyway) way with "find" to select files that
	have been changed more recently than time X (as in the files that
	should be backed up - or in my case, files that have been fetched
	at work via anon cvs, and I want to take home with me ...)
	find -newer is no good for this, as cvs back dates files to the
	time they were either updated in the repository, or more likely
	(and even worse for this) the time they were last edited before
	being checked in - which is totally unrelated to whether the file
	was in my checked out copy when I last copied it...
>How-To-Repeat:
	RTFM or UTSL.
>Fix:
	Apply the following patch.   Seems to work just fine.
	Feel free to change the "updated" label to something more
	reasonable ... I couldn't think of anything.
