/**
* The Date header field reflects the time when the request or response is
* first sent. Retransmissions have the same Date header field value as the
* original. The Date header field contains the date and time. Unlike
* HTTP/1.1, SIP only supports the most recent
* RFC 1123 format for dates.
* SIP restricts the time zone in SIP-date to "GMT", while RFC 1123 allows any
* time zone.
*
* The Date header field can be used by simple end systems without a
* battery-backed clock to acquire a notion of current time. However, in its
* GMT form, it requires clients to know their offset from GMT.
*
* Example:
* Date: Sat, 13 Nov 2010 23:29:00 GMT
