Ah!  But the *creation time* is changed when you move the file.
(Creation time is a misnomer;  the real meaning of this field is
"last change to inode").

Thus, the following find command will pick up all files for a daily
incremental backup:

	find / -mtime -1 -print -o -ctime -1 -print ...

or, if you have the mods to find that allow switches like -newercm, use

	find / -newercm /.lastinc -print -newermm /.lastinc -print

(I think I have the character order right;  it might be -newermc).
