RFC 9557: Date and Time on the Internet: Timestamps with Additional Information
Proposed Standard
U. Sharma
C. Bormann
April 2024
IETF publication
Applications and Real-Time Area
Abstract
This document defines an extension to the timestamp format defined in RFC 3339 for representing additional information, including a time zone.
It updates RFC 3339 in the specific interpretation of the local offset Z, which is no longer understood to "imply that UTC is the preferred reference point for the specified time".

RFC 8186: Support of the IEEE 1588 Timestamp Format in a Two-Way Active Measurement Protocol (TWAMP)
Proposed Standard
G. Mirsky
I. Meilik
June 2017
IETF publication
Operations and Management Area
Abstract
This document describes an OPTIONAL feature for active performance measurement protocols that allows use of the Precision Time Protocol timestamp format defined in IEEE 1588v2, as an alternative to the Network Time Protocol that is currently used.

RFC 6019: BinaryTime: An Alternate Format for Representing Date and Time in ASN.1
Proposed Standard
R. Housley
September 2010
IETF publication
General Area
Abstract
This document specifies a new ASN.1 type for representing time: BinaryTime. This document also specifies an alternate to the signing-time attribute for use with the Cryptographic Message Syntax (CMS) SignedData and AuthenticatedData content types; the binary-signing-time attribute uses BinaryTime. CMS and the signing-time attribute are defined in RFC 5652. [STANDARDS-TRACK]

RFC 4049: BinaryTime: An Alternate Format for Representing Date and Time in ASN.1
Experimental

April 2005
IETF publication
Abstract
This document specifies a new ASN.1 type for representing time: BinaryTime. This document also specifies an alternate to the signing-time attribute for use with the Cryptographic Message Syntax(CMS) SignedData and AuthenticatedData content types; the binary-signing-time attribute uses BinaryTime. CMS and the signing-time attribute are defined in RFC 3852. This memo defines an Experimental Protocol for the Internet community.

July 2002
IETF publication
Applications Area
Abstract
This document defines a date and time format for use in Internet protocols that is a profile of the ISO 8601 standard for representation of dates and times using the Gregorian calendar.
