[Plugin: Bulk Change Attachment Parent] Change attachment's date/time?

Another attachment field in the WordPress database that is impossible to edit without MySQL is the date/time … could you add the ability to edit that, to this plugin? Or is there any other way to modify it from the Admin interface?

I need this because I’m writing a plugin that selects attachments based on their date/time, and there is no way to edit them that I can find.
