The _apparent_ need (or acceptability) for less precision in dates as they age is not necessarily true. For example, in retrospective review of 'causes and effects' (eg a drug trial) time _intervals_ will be required to be calculatable at optimum precision. A general principle is, surely, that we can't and should not anticipate the future use/value of any of the data!
