Syntax Bytes Type<br />
Alive_Request_Data{<br />
time( )<br />
}<br />
time( ) –The current UTC time clock of the sending device checked as close as possible to<br />
the sending of the message. This is designed to be used by the Splicer and the Server to<br />
check on how well the two systems are time synchronized. It is not expected that this will<br />
allow the systems to synchronize well enough to allow reliable splicing to occur, but the<br />
implementers may use this as they wish. See Section 8.4 for the time( ) structure syntax.<br />
