Inspired by the "internationalize your menubar clock date" hack, here´s the "put the date right in your menubar" hack.
It effectively changes the "show the day of the week" option for the menubar clock to "show the day of the week and date". For example, mine now says "Mon Nov 26 2001 5:40 AM"
Here´s how to do it ... (if you´re cautious, back up Clock.menu or just Clock)
1. Fire up Terminal
2.
cd /System/Library/CoreServices/Menu Extras/Clock.menu/Contents/MacOS/
sudo perl -p -i -e "s/%a /%x /" Clock
3. type in your admin password, obviously, for ´sudo´. If you are typing by hand, be extra sure to include the space after "%a" and the space after "%x".
4. Logout and back in (or kill SystemUIServer, if you´re into that sort of thing).
Voila! Make sure that the "Show the day of the week" option is checked in System Preferences/Date & Time/Menu Bar Clock. Unfortunately, because it´s such a low-level hack, there´s no straightforward way to change the format of the date.
To put it back, change to the same directory and do:
sudo perl -p -i -e "s/%x /%a /" Clock
This is tested to work under 10.1.1. It should work fine on other versions, but no guarantees.
