Well, on last typo found. A 93% moon is no longer incorrectly considered "full."
Oops - when I made the fix, I simplified some of the logic used to determine the moon phase. But when I did that, I accidently made it so that the moon phase from 100% (Full) - 95% (Waning) was considered the Last Quarter.
This has been fixed, now.
This update attempts to bring the moon phase data inline with the Vana'diel moon phase. It is based on Nakti's post which was based on the MithraPride Vana'diel Clock, so ultimately the corrected data comes from Golddess. So thank Nakti for creating the little table, and thank Golddess for figuring out the phases!
This is the first version of the separate clock extension, it used to be a part of the FFXI Skillchains Extension. It is now its own extension.
