After I read this macosxhints.com post, I decided to have a go at something slightly different.
The orginal hint showed how to set up an AppleScript droplet to modify the creation date of a file. But what if you want to sync the modified date and Creation dates instead? This script has been created to do just that. It has evolved from one Daniel A. Shockley provided in a macosxhints comment to the previous hint, and has been extended to fit this purpose.
