parse-iso8601

Arguments: iso8601-text &key start end expanded-digits fraction-digits date

Returns a time-interval or a date-time object based on iso8601-text, which should be a string with suitable contents.

If the iso8601-text argument contains either a #\P, #\R, or #\/, then the return value is equivalent to the following:

(require :datetime)
(use-package :util.date-time)

(time-interval iso8601-text :start start :end end)

Otherwise, the return value is equivalent to the following:

(require :datetime)
(use-package :util.date-time)

(date-time iso8601-text :start start :end end :date date
                          :expanded-digits expanded-digits
                          :fraction-digits fraction-digits)

See time-interval and date-time for details of the keyword arguments.

Examples

(require :datetime)
(use-package :util.date-time)

 (parse-iso8601 "R5/2002-03-01T13:00:00Z/P1Y2M10DT2H30M"))
=> #<time-interval R5/2002-03-01T13:00:00Z/P1Y2M10DT2H30M0S @ ...>

 (parse-iso8601 "19850412T23:20:50")
=> #<date-time "1985-04-12T23:20:50" @ ...>

See date-time.htm for information on support in Allegro CL for parsing and generating time expressions using the ISO 8601 standard.
