Here are my notes on ISO 8601 from one of my Y2K upgrade projects, as of about 1999-06: # ISO 8601 specifies the format for numeric dates and times. The standard # does not cover alphabetic dates, which are language-specific. # References: # http://www.iso.ch/markete/8601.pdf The standard itself # http://www.cl.cam.ac.uk/~mgk25/iso-time.ht A good summary # The complete format is ccyy-mm-dd hh:mm:ss.ffff, where the parts are # century, year, month (in 01..12), day (in 01..31), hour (in 00..23, # or 24 in special cases), minute (00..59), second (00..59, or 60 on # leap seconds), and decimal fractional seconds. Example: # 1999-06-09 13:37:32 +0700 (see below for timezone). # Possible variants are: # Omit parts from the left or right (century, year, seconds, minutes). # Omit the entire date, or the entire time. # Omit the hyphens and colons. # Join the date and time by upper case T rather than blank. # Other punctuation such as / or . is not allowed. # For a week-based code use ccyy-Www-d where the parts are century, year, # week (in 01..53), day (in 1..7, 1 = Monday). Week 01 is the week that # has more days in that year than the previous one, or equivalently for # which January 04 is on Sunday or earlier of that week. Example: # 1997-W05-2 = Tuesday, 28 January 1997. # Same variants as for month-based dates. The day of week can also be # omitted. # The year and day code: ccyy-ddd, where the day is in 001..366. # For timezones append +hh or +hhmm or +hh:mm, or the same with minus, or # "Z" for UTC. Example: Afghanistan time is +0430. James F.
