A data type containing date and/or time information. This data type is a placeholder, as various platforms have differing built-in date-time data types. This data type is intended to handle both precise dates and imprecise dates (e.g., just a year), which would likely be implemented using different data types. Therefore, it is anticipated that this data type will be replaced by a different data type when transforming to a particular implementation platform. Note that the FHIM has one data type that can be used to hold a date, a date-and-time, or just a time. In contrast FHIR has four data types: date, dateTime, time, and instant. The FHIM currently does not distinguish among the levels of precision that might be used in actual implementations, but leaves the datatype broad to handle all possible use cases. The FHIM PointInTime data type is most closely aligned with the FHIR dateTime data type. "A date, or partial date (e.g. just year or year + month) as used in human communication. There is no time zone. Dates SHALL be valid dates" - HL7 FHIR, date "A date, date-time or partial date (e.g. just year or year + month) as used in human communication. If hours and minutes are specified, a time zone SHALL be populated. ... Dates SHALL be valid dates…." - HL7 FHIR, dateTime "A time during the day, with no date specified (can be converted to a Duration since midnight). … A time zone [is not allowed]." - HL7 FHIR, time "An instant in time - known at least to the second and always includes a time zone. Note: This is intended for precisely observed times (typically system logs etc.), and not human-reported times - for them, use date and dateTime. instant is a more constrained dateTime" - HL7 FHIR, instant
