Re: [Jigs-devel] More on off-by-one date error

[Brent B. <br...@ma...>]

Stupid pine automagically picks mcmahan@cs not the list.

Anyway, I think this is a solved problem.  I have looked into a bit more 
and it appears to do the right thing.  The major problem here is that exif 
stores months starting from index 1 (Jan == 1, Feb ==2), whereas Java 
stores dates with index 0 (Jan == 0, Feb == 1).  I changed the 
TimeDateUtil code to reflect this some time ago, but certainly not before 
whitman, etc, which is why there is that distiction.  As for the 10d... 
The jurys still out on whether or not you can correctly set the date on 
that thing! :)
