smux_trap() contains an argument whose use appears to be to set sysUpTime.0/timestamp field in SNMP trap. However, this value is not used in smux_trap(). Moreover, it is expected that this field is the value of sysUpTime.0 when the trap was sent and not any other time related to the trap. To avoid any confusion, we remove this field from the signature of the function.
