OS X: add the date to the menu bar in Leopard
There are several tutorials to add the date entry to the menu bar in OS X. Unfortunately none worked in Leopard, hopefully this one will work for you as it did for me.
1. Go to System Preferences
2. Click on International > Formats
3. In the dates section, click on Customize
4. Pick and mix any combination of data you like
5. When you are happy with it all, select it all and copy it (CMD + V)
6. In the section times, click on Customize
7. select Medium and paste your date style where you want it to appear and click ok
8. Now the trick to getting this to work in Leopard, in System Preferences > Date & Time > Clock
9. Remove the tick next to "Show date and time in menu bar" and add it back again.
It is this last step (#9) that makes the date appear in Leopard (at least for me)
Feedback welcome.
