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.

Explanation of the columns that may appear on this page:
Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies |
System | The source of the definition of the code (when the value set draws in codes defined elsewhere) |
Code | The code (used as the code in the resource instance) |
Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application |
Definition | An explanation of the meaning of the concept |
Comments | Additional notes about how to use the code |
