1. A user equipment, UE, apparatus for computing, comprising:one or more processors;a clock coupled to the one or more processors;a communication controller coupled to the one or more processors; andtransmit logic to be operated by the one or more processors to:
send a first message via the communication controller to a second communication controller of a second UE apparatus;
cause a time value from the UE apparatus clock to be stored, the time value to indicate a time when the communication controller sent the first message, wherein upon receipt of the first message by the second communication controller the second UE apparatus is to start a timer; and
send a second message to the second communication controller of the second UE apparatus, the second message to include the stored time value, where upon receipt of the second message by the second communication controller, the second UE apparatus is to update a clock of the second UE apparatus based upon the stored time value and a value of the timer.
