Remove support for Legacy date/time (XEP-0090 and XEP-0091).

These specifications are deprecated long enough (since 2007) in favor of XEP-202/203.

-/**
- * Implements the TYPE_IQ jabber:iq:time protocol (time info) as
- * as defined by JEP-0090. Allows Jabber entities to query each
- * other's local time.  The server will respond with its local time.
- * <h2>Assumptions</h2>
- * This handler assumes that the time request is addressed to itself.
- * An appropriate TYPE_IQ tag matcher should be placed in front of this
- * one to route TYPE_IQ time requests not addressed to the server to
- * another channel (probably for direct delivery to the recipient).
- * <h2>Warning</h2>
- * There should be a way of determining whether a session has
- * authorization to access this feature. I'm not sure it is a good
- * idea to do authorization in each handler. It would be nice if
- * the framework could assert authorization policies across channels.
