The most usual uses are:
* DV_DURATION - time periods in the 'social' timescale, e.g. hours,
days, weeks, months, years - e.g. pregnancy, Expected Date of
Delivery, duration of migraine
* DV_QUANTITY - short time periods, being treated more
mathematically, e.g. seconds or smaller, minutes and hours
both can be used for computation and can be inter-converted.
