I'm pretty sure it does, since the names of the eras come from 
somewhere. If, for example, you set your system clock to some time in 
1870 and turn on the Japanese calendar in the International preference 
pane, then the year & era will be "3 Meiji" instead of 1870. I was 
trying to figure out where these eras started so I didn't have to poll 
the system for the data.

But it doesn't matter too much, since I was able to work around the 
problem by using -[NSDateFormatter eraSymbols], where the symbol 
indexes are a perfect match for the era numbers on the Japanese 
calendar. I was hoping it would be possible to not make this 
assumption, but at least it solves the problem for now...
