I agree with both aspects of Thomas's argument. In terms of future practical "longitudinal" use of the data, the effective time-precision will be set much more by the month than the day. However, it's also true that there _may_ be some other (presently-unimagined) use for the more-precisely defined day - which argues in favour of it being recorded.
