NAME

DateTime::Format::JSON::MicrosoftDateFormat - Parse and format JSON MicrosoftDateFormat strings

SYNOPSIS


            

              
              
use DateTime::Format::JSON::MicrosoftDateFormat;
my $formatter = DateTime::Format::JSON::MicrosoftDateFormat->new;
my $dt        = $formatter->parse_datetime("/Date(1392089278000-0600)/"); #2014-02-10T21:27:58Z
my $dt        = $formatter->parse_datetime("/Date(1392067678000)/");      #2014-02-10T21:27:58Z
say $formatter->format_datetime($dt);                                     #/Date(1392067678000)/

The Perl One Liner


            

              
              
perl -MDateTime::Format::JSON::MicrosoftDateFormat -e 'print DateTime::Format::JSON::MicrosoftDateFormat->new->parse_datetime(shift), "\n";' '/Date(1392606509000-0500)/'

DESCRIPTION

This module understands the JSON MicrosoftDateFormat date/time format. e.g. /Date(1392067678000)/

USAGE

Note: The usage of MicrosoftDateFormat is deprecated for new JSON services. Please use ISO 8601 for all new development.

From RFC 7493 (The I-JSON Message Format):


            

              
              
Protocols often contain data items that are designed to contain timestamps or time durations. It
is RECOMMENDED that all such data items be expressed as string values in ISO 8601 format,
as specified in RFC 3339, with the additional restrictions that uppercase rather than lowercase
letters be used, that the timezone be included not defaulted, and that optional trailing seconds
be included even when their value is "00". It is also RECOMMENDED that all data items
containing time durations conform to the "duration" production in Appendix A of RFC 3339, with
the same additional restrictions.

import

Installs the TO_JSON method into the DateTime namespace when requested


            

              
              
use DateTime::Format::JSON::MicrosoftDateFormat (to_json => 1); #TO_JSON method installed in DateTime package
use DateTime::Format::JSON::MicrosoftDateFormat;                #TO_JSON method not installed by default

Use the imported DateTime::TO_JSON method and the JSON->convert_blessed options to seamlessly convert DateTime objects to the JSON MicrosoftDateFormat for use in creating encoded JSON structures.


            

              
              
use JSON;
use DateTime;
use DateTime::Format::JSON::MicrosoftDateFormat (to_json=>1);
my $formatter = DateTime::Format::JSON::MicrosoftDateFormat->new;
my $json      = JSON->new->convert_blessed->pretty;
my $dt        = DateTime->now(formatter=>$formatter);
print $json->encode({now=>$dt}); #prints {"now" : "/Date(1392747671000)/"}

CONSTRUCTOR

METHODS

parse_datetime

Returns a DateTime object from the given string


            

              
              
use DateTime::Format::JSON::MicrosoftDateFormat;
my $parser = DateTime::Format::JSON::MicrosoftDateFormat->new;
my $dt     = $parser->parse_datetime("/Date(1392606509000)/");
print "$dt\n";

format_datetime

Returns a JSON formatted date string for the passed DateTime object


            

              
              
my $dt        = DateTime->now;
my $formatter = DateTime::Format::JSON::MicrosoftDateFormat->new;
print $formatter->format_datetime($dt), "\n";

However, format_datetime is typically used like this...


            

              
              
use DateTime;
use DateTime::Format::JSON::MicrosoftDateFormat;
my $formatter = DateTime::Format::JSON::MicrosoftDateFormat->new;
my $dt        = DateTime->now;
$dt->set_formatter($formatter);
print "$dt\n"; #prints /Date(1392747078000)/

Note: The format_datetime method returns all dates as UTC and does does not support time zone offset in output as it is not well supported in the Microsoft stack e.g. /Date(1392747078000-0500)/
