The format for the parameter data returned by the SET TIMESTAMP command is shown in table 193.

TIMESTAMP field

The TIMESTAMP field specifies the value to which a device clock shall be initialized (see SPC-5). The timestamp should be the number of milli-

seconds that have elapsed since midnight, 1 January 1970 UT. If the most significant byte in the TIMESTAMP field is greater than F0h, the device

server shall terminate the command with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code

set to INVALID FIELD IN PARAMETER LIST.

On successful completion of a SET TIMESTAMP command the device server shall establish a unit attention condition for the initiator port asso-

ciated with every I_T nexus except the I_T nexus on which the SETTIMESTAMP command was received (see SAM-5), with the additional sense

code set to TIMESTAMP CHANGED.
