Enum GuestClockPolicy 

pub enum GuestClockPolicy {
    Sync,
    Off,
}

Host control over the guest wall clock (CLOCK_REALTIME).

Serializes as the lowercase variant name ("sync", "off") to match the CLI spelling. The guest monotonic clock is never adjusted by either policy.

Variants

Sync

Keep the guest wall clock in step with the host.

The runtime sends the host time at boot and about once a minute, and steps the guest clock to host time when a full snapshot is restored or a paused sandbox resumes.

Off

Never set the guest wall clock after boot.

The guest keeps the time it read at boot and advances it on its own. A restored full snapshot continues from the captured guest time instead of jumping to host time.
