Extension: Timezone Offset

FHIR Infrastructure Work Group   Maturity Level : 1 Informative Use Context : Any

URL for this extension:


http://hl7.org/fhir/StructureDefinition/tz-offset

Status: draft. Extension maintained by: Health Level Seven International (FHIR Infrastructure)

Timezone offset, for dates where timezone is not allowed as part of the base date.

The format must either be 'Z' or +/-HH:NN. This is not allowed on the base date because many implementations have no way to carry a timezone on the base date structure.

Context of Use: Use on Element ID date
