#### Times

Before going into detail with the exposed FHIR APIs it's important to note that all dates and timestamps mentioned in these APIs are in
[UTC](https://en.wikipedia.org/wiki/Coordinated_Universal_Time). This means that any localization of these dates and timestamps will need to happen on the client side. For exact details on how to fill these, we recommend looking into the
[FHIR documentation](http://hl7.org/fhir/R4/datatypes.html#dateTime)
