I've seen 2 issues w/ exfat timestamps - discovered by xfstests generic/003

1) time granularity is set wrong, so subsecond timestamps change when
   an inode cycles out of memory and is reread from disk

2) the disk format doesn't seem to support subsecond atime, so a similar
   problem exists there.e

The last xfstests generic/003 issue is re: change time but exfat doesn't
really support change times (?) so that'll be a test workaround.

Applied.
