<description
value="This value set includes all common UCUM codes used for Time Duration Units - 'a' (years), 'mo' (months), 'd' (days), 'h' (hours), 'min' (minutes), 's' (seconds), and 'ms' (milliseconds). NOTE: This value set is the same as the duration units value set, except that it does not include weeks, because weeks are not a valid precision for a datetime, time, or instant value."/>
