Up until now, leap second announcements were handled in user space,
and the kernel played no role.

I thought that the whole point of using a VM is t

Ioctl PTP_SYS_OFFSET_PRECISE2 provides cross-timestamping of device time
and system time. This can be used for virtualization where (virtualization)
