Not currently addressed, but possibly covered by the definition ofĪdditional map keys for the map inside the tag: Microseconds at the time of writing (and progressively becoming Representation of times, limiting resolution to approximately Tag 1 only provides for integer and up to binary64 floating point O Additional resolution for epoch-based time (as in tag 1). Objectives that go beyond the original tags 0 and 1: That should be familiar to connoisseurs of precise time referencesįor the time tag, the present specification addresses the following This specification uses a number of terms Notation familiar from the programming language C (including C++14'sĠbnnn binary literals), except that the operator "**" stands forĪdditional information about the complexities of time representationĬan be found in.

It is intended as the reference document for the IANA Tag for time that allows a more elaborate representation of time, andĪnticipates the definition of related CBOR tags for duration and time RFC 7049 defines two tags for time: CBOR tag 0 ( RFC3339 time) and tagġ (Posix time, int or float). In CBOR, one point of extensibility is the definition of CBOR tags.
