Is there a way to copy to and paste from clipboard?

Looks like Pasteboard.stringContents will let you see what's already on the clipboard, but I don't see a way to automate copying or pasting. My use-case is that I'd like to generate a string with some javascript, using current time and date, insert it into the clipboard, so that I can either automatically paste or then hit CMD-V to paste.
