      Sorry to reply to my own posting but the soapversion() call doesn't
      work on a server in the same way as a client. Try

      SOAP::Lite->soapversion('1.2');

      /before/ creating your server daemon.

        It seems completely ignored, I get the same namespace.

        My code:

        SOAP::Lite->soapversion('1.2');
        my $daemon = SOAP::Transport::HTTP::CGI
        -> dispatch_to('/local/lib/soap', '*',
        '', '');
        $daemon->handle;

        My server (Apache 1 + mod_perl):

        <Location /soap>
        SetHandler perl-script
        PerlHandler Apache::Registry
        PerlSendHeader On
        Options +ExecCGI
        DirectoryIndex dispatcher
        </Location>

        My result:

          Again, I see no impedement to getting a result from a server, and then
          fetching a string value from somewhere in the the result, and passing it
          through to Date::Manip to parse the date more effectively... or hell
          writing my own regular expression like:

          my ($year,$month,$day,$hour,$min,$sec,$ms,$timezone) = ($date =~
          /^(\d\d\d\d)-(\d\d)-(\d\d)T(\d\d):(\d\d):(\d\d)(\.\d\d\d)?(Z|([+-]\d\d:\d\d))?$/);

          Fair enough... here is a little bit on datetimes with SOAP::Lite... A recent module to CPAN seems to help address the problem:

            Fair enough... here is a little bit on datetimes with SOAP::Lite...

            A recent module to CPAN seems to help address the problem:
            http://search.cpan.org/~mcmahon/SOAP-DateTime-0.01/

            From the README: "This is a little utility module that converts dates
            into the format required by the SOAP 'xsd:dateTime' type. It's just a
            dumb little wrapper around Date::Manip, because that's the lazy way to
            make sure that we are forgiving in what we accept."

            So there is also Date::Manip (obviously).
            http://search.cpan.org/~sbeck/DateManip-5.42a/Manip.pod

            Bottom line, SOAP::Lite doesn't (since Perl is so loosely typed) do any
            type deserialization for you. Not to anything but a SCALAR. Perhaps that
            is something we should more clearly document and provide workarounds for.

            The flip side of course is that the next version of SOAP::Lite, which
            will ship with wsdl2perl, will handle dates more gracefully and
            recognize all of their permutations. From the source of the next release
            of SOAP::Lite:

            _typelookup => {
            ...
            'gMonth' =>
            [35, sub { $_[0] =~ /^--\d\d--(-\d\d:\d\d)?$/; }, 'as_gMonth'],
            'gDay' =>
            [40, sub { $_[0] =~ /^---\d\d(-\d\d:\d\d)?$/; }, 'as_gDay'],
            'gYear' =>
            [45, sub { $_[0] =~ /^-?\d\d\d\d(-\d\d:\d\d)?$/; }, 'as_gYear'],
            'gMonthDay' =>
            [50, sub { $_[0] =~ /^-\d\d-\d\d(-\d\d:\d\d)?$/; },

              I know it and mentioned it in my first message. It only handles
              serialization, my problem being the deserialization.

              I do not see the connection with my problem. Python and PHP are no
              more typed than Perl and both can deserialize xsd:dateTime (they just
              produce a string for a type they do not know, that I parse after). Why
              can't SOAP::Lite do the same?
