    abstract =  {The Concise Binary Object Representation (CBOR, RFC 7049) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. In CBOR, one point of extensibility is the definition of CBOR tags. RFC 7049 defines two tags for time: CBOR tag 0 (RFC3339 time) and tag 1 (Posix time {[}TIME\_T{]}, int or float). Since then, additional requirements have become known. The present document defines a CBOR tag for time that allows a more elaborate representation of time, and anticipates the definition of related CBOR tags for duration and time period. It is intended as the reference document for the IANA registration of the CBOR tags defined.},
