Grouped time scale units can be applied to date and time representations as replacements for any time scale unit components as long as the resulting expression is a valid one.
EXAMPLE 1’2018Y4G60DU6D’ is a valid date expression that refers to the date year 2018, 6th day of the 4th 60-day group, which is the 186th ordinal day of year (in the Gregorian calendar, the 186th ordinal day is July 5th in a common year and July 6th in a leap year).
EXAMPLE 2 ‘2018Y9M2DT3GT8HU0H30M’ is a valid date and time expression that refers to the date year 2018, September 2nd, 16:30 (30 minutes into the third 8-hour period). While the inner expression ‘0H’ is supplied,it can be omitted in accordance with 7.10.
EXAMPLE 3 ‘2018-02-2G14DU’ (implicit form) and ‘2018Y2M2G14DU’ (explicit form) are complete date expressions that indicate “the second fortnight of February 2018″, as specified by the rule ‘ group every 14 days,second group”.
EXAMPLE 4 ‘2018-03-3G10DU’ (implicit form) and ‘2018Y3M3G10DU’ (explicit form) are complete date expressions that indicate “the third 10-day block of March in 2018”, as specified by the rule “group every 10 days,third group”. A 10-day block is a time grouping commonly used in East Asia.
EXAMPLE 5 16:1GT15MU (implicit form) and ‘T16H1GT15MU’ (explicit form) are time expressions that indicate “the first quarter-hour of 16:00”, as specified by the rule “group every 15 minutes, first group”.
EXAMPLE 6 ‘2018-1G6MU’ (implicit form) and 2018Y1G6MU’ (explicit form) are date expressions of six-monthly precision that indicate “the first half of 2018”, as specified by the rule “group every 6 months, first group”, and therefore the grouping is specified in the [month] field. The resulting time interval is equivalent to the time interval expression ‘2018-01-01/2018-06-30’ and the sub-year grouping expression ‘2018-40’.
Date and time representations can incorporate the grouped time scale units by applying rules from 5.2 and 5.3 to a date and time representation described within this document and ISO 8601-1, by replacing a time scale unit component in the representations with [group].ISO 8601-2 pdf free download.
