System-wide Insert Date & Time
I need to be able to insert both the date and time into applications system-wide. There was, at one time, a System Service that allowed for that action. It appears to be gone now and I really would like to have that option back. I've tried some of the Automator suggestions, none of which worked. I'm not a coder, so the Scripts option appears to be the only other way to do it, but I've no idea how to craft a script that would accomplish what I'm after. Anyone have suggestions or comments? I'm amazed that Apple chose to remove that built-in system service.
