Another interesting observation. The time is almost always
like this. Another very common version is 0.199999:

[ 0.189999] ACPI: PCI Interrupt Link [LNKD] (IRQs 5 10 *11)
[ 0.193333] HEST: Table is not found!
[ 0.193333] vgaarb: device added: PCI:0000:00:02.0,decodes=io+mem,owns=io+mem,locks=none
[ 0.196666] vgaarb: loaded
[ 0.196666] PCI: Using ACPI for IRQ routing
[ 0.199999] Switching to clocksource kvm-clock
[ 0.199999] pnp: PnP ACPI init
[ 0.199999] ACPI: bus type pnp registered
[ 0.199999] pnp: PnP ACPI: found 8 devices
[ 0.199999] ACPI: ACPI bus type pnp unregistered
[ 0.199999] PnPBIOS: Disabled
...

This shows much more often than any other value.

Thanks!
