First I've released a new version of Final Fantasy XI Timer for Palm
with World Time that displays the current time from the Japanese, Pacific, Eastern and United Kingdom time zones and added the EXP chain countdown to the countdown timer.
It has been also updated to calculate Daylight Savings Time correctly for pre PalmOS 4.0 devices. If you had to adjust the time in the "Time Adjustment" for Daylight Savings Time, you'll have to take out the adjustment.
I'll see about adding a skill cap calculator with the skill chain calculator. I'll put the gardening log on my list. The features I add are coloured by how I play the game and what I need as a Black Mage.
I cannot port this to other OSes. It is written for the native PalmOS API and most of the work involves getting the interface right. It would be easier to start fresh then try to get this to work for other devices.
If you buy an old Palm III and Palm V the Final Fantasy XI Timer should work on it and you can buy those old devices on eBay for prices that may be conpetative with the offical Final Fantasy XI clock.
