How to change language of hover in date zimlet

[oldboy]

Hi, im new to zimbra, and i installed it in a test server and everything is working great, except for the date-time zimlet the one where you:
Mouse-over a date or time, and see what's in your calendar;

i mean its nothing wrong with it, but i need that zimbra recognaize words in spanish, like "Hoy" instead of "Today", or "Mañana" instead of "Tomorrow", so when i pass my mouse-over the word Mañana zimbra shows what is in my calender
I also need to change the date formats from mm/dd/yyyy to dd/mm/yyyy

I cant find any zimlet where i can do this... i already modified the phone zimlet so we can work with our phone numbers...

Any help would be greatly apreciated

Oh and by the way ZImbra ROCKS its a really nice piece of SW thank you guys

In 3.1.x this is hard coded, so it's hard to change. 3.2 and beyond expose this as a Zimlet so you can just edit the JS code.

In what file can this change be done?
