/**
 * QEMUClockType:
 *
 * The following clock types are available:
 *
 * @QEMU_CLOCK_REALTIME: Real time clock
 *
 * The real time clock should be used only for stuff which does not
 * change the virtual machine state, as it is run even if the virtual
 * machine is stopped. The real time clock has a frequency of 1000
 * Hz.
 *
 * @QEMU_CLOCK_VIRTUAL: virtual clock
 *
 * The virtual clock is only run during the emulation. It is stopped
 * when the virtual machine is stopped. Virtual timers use a high
 * precision clock, usually cpu cycles (use ticks_per_sec).
 *
 * @QEMU_CLOCK_HOST: host clock
 *
 * The host clock should be use for device models that emulate accurate
 * real time sources. It will continue to run when the virtual machine
 * is suspended, and it will reflect system time changes the host may
 * undergo (e.g. due to NTP). The host clock has the same precision as
 * the virtual clock.
