Topic: time of day in observation

Thanks for the reply @Eric Haas and @Grahame Grieve . Ok so I don't need extension for this. I got confused and tried to search for the completely wrong thing. This event timing value set got me confused because at the beginning it seemed like something I was looking for. Using component seems to be answer to most of my questions. So could it just be presented like this:
"component": [
{
"code": {
"coding": [
{
"code": "272106006",
"display": "Temporal periods of day (qualifier value)",
"system": "http://snomed.info/sct"
},
{
"code": "73775008",
"display": "Morning (qualifier value)",
"system": "http://snomed.info/sct"
}
]
}
}
]
or does the morning, day, evening or night have to be valueCodeableConcept like this:
"component": [
{
"code": {
"coding": [
{
"code": "272106006",
"display": "Temporal periods of day (qualifier value)",
"system": "http://snomed.info/sct"
}
]
},
"valueCodeableConcept": {
"coding": [
{
"code": "3157002",
"display": "Evening (qualifier value)",
"system": "http://snomed.info/sct"
}
]
}
}
],

Can someone please give comments does this look like valid FHIR way to present time of day of measurement? So I need to store (morning, day, evening or night) in addition to effectiveDateTime.

The first example is a bit suspect. Multiple codings should be encodings of the same thing. It's fine for an application to pay attention to one coding and ignore the rest - it's not used to post-coordinate. If you want to post-coordinate, you do that all in one code. The second could work.
Eric Haas (Jan 30 2019 at 20:42):
As lloyd said component is a name value pair. Its a dependent observation....
so
component.code = time of day
component.valuestring|valueCodeableConcept = 'morning'
Lauri Karppinen (Jan 31 2019 at 06:17):
I will go with the second option. component.valueCodableConcept. Thanks a lot for the confirmation :)
