this looks sensible enough to me

note i i was looking for a model of how days, weeks, months, years may be
rolled up in a hierarchical dimension, but i think I'm happy with just
being able to declare the type of each level - and declare simple
skos:broader/narrower relationships between dimension components - and
leave it to additional properties in a more generalised vocabulary (not yet
available) to define the functions.

Its useful to be able to specify a month as a start or end of a period -
but perhaps the more general approach is to use the ISO 8601  time
microformat indicating precision level.

 i.e. we are not making it owl:Time's problem to define the relationship
between days, months, years (because it cant also handle weeks, years,
hours, days,weeks,months or other implementation choices about what rolled
up dimensions are available.)
