- * Clock management:
- * """""""""""""""""
- *
- * The qtest client is completely in charge of the QEMU_CLOCK_VIRTUAL.  qtest commands
- * let you adjust the value of the clock (monotonically).  All the commands
- * return the current value of the clock in nanoseconds.
- *
- * .. code-block:: none
- *
- *  > clock_step
- *  < OK VALUE
- *
- * Advance the clock to the next deadline.  Useful when waiting for
- * asynchronous events.
- *
- * .. code-block:: none
- *
- *  > clock_step NS
- *  < OK VALUE
- *
- * Advance the clock by NS nanoseconds.
