It seems that that after a host is suspended for several hours and resumed while a bhyve VM is running, then time counting becomes rather broken in the VM. With Linux VMs I observe that date(1) keeps reporting stale pre-suspend time and thread scheduling is broken, new processes can not be started, etc. -- Andriy Gapon
