I don't know why you say it is "under review." ISO 8601 is in the 3rd (2004) edition, and is widely used for data interchange that must be both computer and human readable. It disclaims itself as a standard in flowing text; it is for use in data fields. If only computers need to read it, Unix time is probably preferred.
Incidently the format "Era-Year-Month-Date H hr:m:s" is wrong. There is no "era" field. The basic format requires 4 digit non-negative year, and expanded format allows five or more year digits with a mandatory positive or negative sign to handle years outside 0000 to 9999. In concatenated date/time fields, no space is permitted and the required separator is "T" not "H". Thus yyyy-mm-ddThh:mm:ss that should be followed by a "Z" for UTC time or a signed field with hours (and minutes if required) offset from UTC. Any space terminates the field. That requirement sacrifices some human readability for the computer gods. The hyphens and colons may be omitted, although human readability is sacrified, but the "T" is compulsary. Leading zeroes are required where necessary to pad each subfield to the correct length. You should learn it and use it before complaining it is not used. Incidently it declares the Gregorian calendar, it may NOT be used with the Julian calendar or any of your proposed calendar revisions. It contains a brief definition of Gregorian, and requires proleptic Gregorian for dates before the Gregorian calendar was required. ________________________________ From: Brij Bhushan Vij <[email protected]> To: U.S. Metric Association <[email protected]> Sent: Thu, March 28, 2013 12:55:41 AM Subject: [USMA:52561] ISO Representation of Date & Time instant WRE: Re: Date Format John sir: >Era-Year-Month-Date H hr:m:s Between 1975 and today (2013), some 28 years have goneby and ISO format is still under REVIEW.
