Perl's Mojo::XMLRPC and manipulating Mojo::Date format

I was inspired to use Mojo::XMLRPC after reading The Mojolicious Blog - Day 11. I'm having problems with Mojo::Date format.

1. During encode_xmlrpc, <dateTime.iso8601> is 2023-06-14T19:45:48Z. Instead, I need it as: 20230614T22:45:48+0300

2. During decode_xmlrpc, I get an error when <dateTime.iso8601> is 20230608T12:00:00+0000:

Garbage at end of string in strptime: +0000 at /usr/local/opt/perl/lib/perl5/5.36/darwin-thread-multi-2level/Time/Piece.pm line 598.
Perhaps a format flag did not match the actual input? at /usr/local/opt/perl/lib/perl5/5.36/darwin-thread-multi-2level/Time/Piece.pm line 598.

EDIT: I believe a missing '%H:%M:%S%z' at the front of $time_format array in XMLRPC.pm is my issue (?)

How can I instruct Mojo::XMLRPC (or Mojo::Date?) to use the desired DateTime format?

Sample code below:

#!/usr/bin/env perl
use Mojo::XMLRPC qw[encode_xmlrpc decode_xmlrpc];
use Data::Dumper;
my $e = encode_xmlrpc(call => TaregtMethod => {originTimeStamp=>Mojo::Date->new(time)});
say STDERR Dumper($e);
my $xml = <<'XML';
<?xml version="1.0" encoding="utf-8"?>
<methodResponse>
  <params>
    <param>
      <value>
        <struct>
          <member>
            <name>activationDate</name>
            <value>
              <dateTime.iso8601>20230608T12:00:00+0000</dateTime.iso8601>
            </value>
          </member>
        </struct>
      </value>
    </param>
  </params>
</methodResponse>
XML
my $d = decode_xmlrpc($xml);
say STDERR Dumper($d);

The problem is at the other end.

It's not configurable, and that's not a valid iso8601 serialization.

That's to be expected since the string isn't a valid iso8601 serialization.

Valid iso8601 formats can be found in the documentation for DateTime::Format::ISO8601.

Mojo::XMLRPC doesn't accept all of them, and it accepts many other formats that aren't part of iso8601.
