sort begin_time not working as expected

[edencorbin]

It's likely I'm calling something wrong, however, the following is returning only expired subscriptions as intended, but not only those updated between the date range specified. I'm having the same issue using created_at, any suggestions?

var filter = {
state: 'expired',
sort: 'updated_at',
order: 'desc',
begin_time: '2016-11-01',
end_time: '2016-11-03'
};
recurly.subscriptions.list(function(output){
return resolve(output);
}, filter);
});

Upgrade to a version of the package that uses version 2.4 of the recurly API. begin_time/end_time features are supported starting from that version; earlier versions of the API will just ignore the begin_time and end_time params.
