My version (forked from Sean's) compiles under ERL OTP 18. This is a simple fix of a few typespecs.

erlang_iso8601

Formats and parses ISO 8601 dates.

Usage

Add it to your rebar.config deps:

{'iso8601',    ".*",    {git, "git@github.com: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}}

Known deficiencies

• Does not support expanded year representation.
• Does not support fractional times.
• Does not support ordinal dates.
• Does not support intervals.
