Issue

HL7 Data types allow for time ranges to be specified by any two of low, high, center and width. There are six different combinations here. I have found only two of the six to be necessary: low and high, or width alone when a time range is known, but not it's anchors.

Recommendation

Rationale

The rationale for constaining this is that it dramatically simplifies how the information is stored without any loss in what is conveyed.


Discussion

Recommended Action Items

Resolution
