<dt><code>utc</code></dt>
<dd>
The guest clock will always be synchronized to UTC when
booted</dd>
<dt><code>localtime</code></dt>
<dd>
The guest clock will be synchronized to the host's configured
timezone when booted, if any.
</dd>
<dt><code>timezone</code></dt>
<dd>
The guest clock will be synchronized to the requested timezone
using the <code>timezone</code> attribute.
</dd>
<dt><code>variable</code></dt>
<dd>
The guest clock will have an arbitrary offset applied
relative to UTC. The delta relative to UTC is specified
in seconds, using the <code>adjustment</code> attribute.
The guest is free to adjust the RTC over time an expect
that it will be honoured at next reboot. This is in
contrast to 'utc' mode, where the RTC adjustments are
lost at each reboot.

NB, at time of writing, only QEMU supports the variable
clock mode, or custom timezones.
