http://tools.ietf.org/html/rfc3261#section-20.38
--------------------------------------------------------
RFC 3261 - 20.38 Timestamp
The Timestamp header field describes when the UAC sent the request to
the UAS.
See Section 8.2.6 for details on how to generate a response to a
request that contains the header field. Although there is no
normative behavior defined here that makes use of the header, it
allows for extensions or SIP applications to obtain RTT estimates.
Example:
Timestamp: 54
--------------------------------------------------------
Kamailio does not support such header (it just ignores it).

8.2.6.1 Sending a Provisional Response
[...]
When a 100 (Trying) response is generated, any Timestamp header field
present in the request MUST be copied into this 100 (Trying)
response. If there is a delay in generating the response, the UAS
SHOULD add a delay value into the Timestamp value in the response.
This value MUST contain the difference between the time of sending of
the response and receipt of the request, measured in seconds.
