Greg,

thanks for applying changes. Here is next batch of incremental
patches for ds1337. These were created against 2.6.12-rc2 patched with
ds1337 [123]/4. Changes were discussed with James Chapman privately
and he sent me his Signed-off-by line for submition.

Make time format consistent with other RTC drivers.
