statis used to read file's modification date and awk is used to filter files that were modified between 9:00 and 17:30. If this code gives you proper results, then you can copy those files using:

Code:

stat -c "%y %n" * | awk -F"[ :]" '$2>=9&&$2<17||$2==17&&$3<=30{print $6}' | xargs -i cp {} /somewhere/else
