The easiest way for the xfs is just to work in UTC and return UTC 
timestamps. The kernel do all conversion calculations for Fxattr() and 
Fstat64(), the xfs is not affected at all. The only thing the xfs must do 
is to set the FS_EXT_3 flag (e.g. returning UTC timestamps and implement 
stat64).

Just take a look into the ext2 xfs (e_getxattr() and e_stat64() inside 
ext2sys.c).

http://sparemint.org/cgi-bin/cvsweb/freemint/sys/xfs/ext2fs/ext2sys.c?rev=1.16&content-type=text/x-cvsweb-markup

The big advantage too: no need for any time conversion as stat() work with 
UTC timestamps too.

The kernel support this since 1.15.4 ...

And even older kernels can easily supported. The ext2 implement the 
Fxattr() if working not in UTC too (the else code path).
