ISO 8601-1:2019/Amd 1:2022 (2022)

Date and time — Representations for information interchange — Part 1: Basic rules — Amendment 1: Technical corrections

PublishedStage 60.60

Introduction

The published version of ISO 8601-1:2019 contained a number of technical errors introduced by the ISO publication process. ISO/TC 154/WG 5 has alerted ISO/CS about those problems during the publication process, but due to how the process proceeds, WG 5 was not allowed to fix them.

CalConnect therefore proposed Amd 1 to fix these issues.

This amendment achieves the following goals with regards to ISO 8601-1:2019:

  1. Corrects technical errors introduced by the ISO publication process in ISO 8601-1:2019.

  2. Correction in newly discovered errors in NOTEs and EXAMPLEs.

  3. Clarification of representation between time scale unit and instant

  4. Definition and usage of "Ending of day" (re-introduction)

Clarifies that the ISO 8601-1 representations are used for representing a time scale unit (with a duration) as well as an instant (with no duration).
