Subject: [SIP] zone-adjustments SDP question

Hi,
I'm developing a SDP parser. In the page 16 of the RFC 2327 says:
"Monthly and yearly repeats cannot currently be directly specified with a single SDP repeat time - instead separate "t" fields should be used to explicitly list the session times. 

z=<adjustment time> <offset> <adjustment time> <offset> ....  "

But in ABNF grammar for SDP in the same document say:

time-fields     =     1*( "t=" start-time space stop-time

                           *(CRLF repeat-fields) CRLF)

                            [zone-adjustments CRLF] 

repeat-fields     =     "r=" repeat-interval space typed-time 

                              1*(space typed-time)

zone-adjustments  =  time space ["-"] typed-time

                               *(space time space ["-"] typed-time)

Why isn't "z=" defined? Should I define it by myself?

Thanks a lot
