    Include the current time of the panic in the panic output
    
    Show both the real and the monotonic time in the panic output when the
    panic is created. This is useful to have something to compare other
    panic timestamps against.
    
    The existing timestamp in the panic output is recorded by the
    management process at the time of receiving the panic from the child
    process. Due to processing and possible core dump creation, this time
    isn't very useful for comparison purposes.
