Are you hand-formatting the JSON, or using RpcPerl's implementation of the
JSON formatter? RpcPerl's test of dates does this:
sub method_getCurrentTimestamp
{
my $now = time;
return {now => $now,
json => new Qooxdoo::JSONRPC::Date ($now)};
}
Looking at the JSONRPC.pm (and attempting to grok perl at the same time), I
see that there's a package for dealing with qooxdoo dates. Its constructor
(or rather, its "new" method) expects a time in epoch format. It does,
however, provide a "set" method that accepts the year, month, ... fields. I
also notice that it needs to do some post-processing (which you have not
done in your example) to remove the surrounding quotes. There should be no
quotes around new Date(...) so when it gets evaluated at the frontend, it
becomes a Date object, not a String.
Since you obviously have a far better grasp of perl than I, I'd suggest that
you take a look at the qooxdoo test methods in
qooxdoo-contrib/RpcPerl/trunk/Qooxdoo/Services/qooxdoo/test.pm and at the
implementation of date handling in
qooxdoo-contrib/RpcPerl/trunk/Qooxdoo/JSONRPC.pm (which begins at line 697).
Also, look at the "really ugly hack" comment near line 509.
Hope that helps.
