javax.sip.header
Interface DateHeader

All Superinterfaces:

java.lang.Cloneable, Header, java.io.Serializable

public interface DateHeader
extends Header

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
