Formats and parses ISO 8601 dates.
Add it to your rebar.config deps:
{'iso8601', ".*", {git, "[email protected]:seansawyer/erlang_iso8601.git", {tag, "1.1.1"}}}
Format a timestamp or calendar datetime tuple:
> iso8601:format(now()).
<<"2012-02-16T01:06:19Z">>
> iso8601:format(calendar:universal_time()).
<<"2012-02-16T01:06:48Z">>
Parse a date string or binary:
> iso8601:parse(<<"2012-02-16T01:06:48Z">>).
{{2012,2,16},{1,6,48}}
> iso8601:parse("2012-02-16T01:06:48Z").
{{2012,2,16},{1,6,48}}
Add 1 hour, 2 minutes and 3 seconds to a datetime tuple:
> Datetime = iso8601:parse(<<"2012-02-16T01:06:48Z">>).
{{2012,2,16},{1,6,48}}
> iso8601:add_time(Datetime, 1, 2, 3).
{{2012,2,16},{2,8,51}}
Get interval datetimes list examples:
> Intervals = iso8601:parse_interval("R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M").
[{{2009,5,11},{15,30,0}},
{{2010,7,21},{18,0,0}},
{{2011,10,1},{20,30,0}},
{{2013,12,11},{23,0,0}},
{{2015,2,22},{1,30,0}}]
> Intervals = iso8601:parse_interval("2008-03-01T13:00:00Z/P1Y2M10DT2H30M").
> Intervals = iso8601:parse_interval("R5/P1Y2M10DT2H30M").
> Intervals = iso8601:parse_interval("R5/P1Y/2008-03-01T13:00:00Z").
