I have to make a script that copy files created in last hour.
It is possible?

CTIME= ???
find . -name "$CFILES" -mtime +$CTIME -exec cp -p {} "$CDIR/tmpold" \;

+n for older than n
-n for newer than n
To find within last hour
use -cmin -60 if your version of find support it
else use touch -t to create a temp_file with a time of one hour ago
then use find's -newer temp_file

Thanks pdreyer.
