time adjustment in seconds or ``reset``
utc
set to ``False`` to use the host local time as the guest clock. Defaults to ``True``.
timezone
synchronize the guest to the correspding timezone
timers
a dictionary associating the timer name with its configuration.
This configuration is a dictionary with the properties ``track``, ``tickpolicy``,
``catchup``, ``frequency``, ``mode``, ``present``, ``slew``, ``threshold`` and ``limit``.
See `libvirt time keeping documentation <https://libvirt.org/formatdomain.html#time-keeping>`_ for the possible values.
