ISO 8601 Strings

Category: Interoperability


Many datasets contain date and timestamp values. Some file formats (such as JSON, CSV) have no native representation for date or timestamps.


We will use ISO 8601 representation for date and timestamps and save them as String fields. Timestamps may include up tp microsecond precision. Timestamps include the offset or Z for UTC. Technical timestamps should be stored in UTC time.

Example date: "2022-12-31"

Example timestamp: "2023-01-03T20:43:18+02:00"

Example timestamp: "2023-01-03T18:43:18.123456Z"
