I have released the first version of Final Fantasy XI Timer for Palm at http://doconnor.homeip.net/ffxi/ Right now all it does it display the current Earth time and the Vana'dial weekday, date and time. It also display the current Universal Time which is useful for make sure the Time Zone is set correctly on your Palm. The web page also has tips on other ways you can use your Palm to help you with Final Fantasy XI.
I expect to add more features.
