NAME

MooseX::Types::ISO8601 - ISO8601 date and duration string type constraints and coercions for Moose

SYNOPSIS

use MooseX::Types::ISO8601 qw/
    ISO8601DateTimeStr
    ISO8601TimeDurationStr
/;

has datetime => (
    is => 'ro',
    isa => ISO8601DateTimeStr,
);

has duration => (
    is => 'ro',
    isa => ISO8601TimeDurationStr,
    coerce => 1,
);

Class->new( datetime => '2012-01-01T00:00:00' );

Class->new( duration => 60 ); # 60s => PT00H01M00S
Class->new( duration => DateTime::Duration->new(%args) )

DESCRIPTION

This module packages several TypeConstraints with coercions for working with ISO8601 date strings and the DateTime suite of objects.

DATE CONSTRAINTS

ISO8601DateStr

An ISO8601 date string. E.g. 2009-06-11

ISO8601TimeStr

An ISO8601 time string. E.g. 12:06:34Z

ISO8601DateTimeStr

An ISO8601 combined datetime string. E.g. 2009-06-11T12:06:34Z

ISO8601DateTimeTZStr

An ISO8601 combined datetime string with a fully specified timezone. E.g. 2009-06-11T12:06:34+00:00

ISO8601StrictDateStr

ISO8601StrictTimeStr

ISO8601StrictDateTimeStr

ISO8601StrictDateTimeTZStr

As above, only in addition to validating the strings against regular expressions, an attempt is made to actually parse the data into a DateTime object. This will catch cases like '2013-02-31' which look correct but do not correspond to real-world values. Note that this is bears a computation penalty.

COERCIONS

The date types will coerce from:

• Num

  The number is treated as a time in seconds since the unix epoch

• DateTime

  The duration represented as a DateTime object.

• Str

  Non-expanded date and time string representations.

  e.g.:-

  20120113 => 2012-01-13 170500Z => 17:05:00Z 20120113T170500Z => 2012-01-13T17:05:00Z

  Representations of UTC time zone (only an offset of zero is supported)

  e.g.:-

  17:05:00+00:00 => 17:05:00Z 17:05:00+00 => 17:05:00Z 170500+0000 => 17:05:00Z

  2012-01-13T17:05:00+00:00 => 2012-01-13T17:05:00Z 2012-01-13T17:05:00+00 => 2012-01-13T17:05:00Z 20120113T170500+0000 => 2012-01-13T17:05:00Z

  Also supports non-standards mixing of expanded and non-expanded representations

  e.g.:-

  2012-01-13T170500Z => 2012-01-13T17:05:00Z 20120113T17:05:00Z => 2012-01-13T17:05:00Z

  In addition, there are coercions from these string types to DateTime.

DURATION CONSTRAINTS

ISO8601DateDurationStr

An ISO8601 date duration string. E.g. P01Y01M01D

ISO8601TimeDurationStr

An ISO8601 time duration string. E.g. PT01H01M01S

ISO8601DateTimeDurationStr

An ISO8601 combined date and time duration string. E.g. P01Y01M01DT01H01M01S

COERCIONS

The duration types will coerce from:

• Num

  The number is treated as a time in seconds

• DateTime::Duration

  The duration represented as a DateTime::Duration object.

The duration types will coerce to:

• Duration

  A DateTime::Duration, i.e. the Duration constraint from MooseX::Types::DateTime.

FEATURES

Fractional seconds

If provided, the number of seconds in time types is represented to microsecond accuracy. A full stop character is used as the decimal separator, which is allowed, but deprecated in preference to the comma character in ISO 8601:2004.

BUGS

Probably full of them, patches are very welcome.

Specifically missing features:

• No timezone support - all times are assumed UTC
• No week number type
• "Basic format", which lacks separator characters, is not supported for reading or writing.
• Tests are rubbish.
