Simple solution with bash script,
just start this script in every folder:
#/bin/bash 
#starting with 1* because all filenames starts with 1
for file in 1*;
do
    echo "Processing $file.."
    
	# getting timestamp from filename, first 10 characters
	tstamp=$(echo "${file}" | cut -c1-10)
	
	# set timestamp to file
	touch -d @"$tstamp" "$file" 
done
