Title:
GCE default NTP configuration uses both leap-smeared and true UTC
sources
Status in cloud-images:
Fix Committed
Status in ntp package in Ubuntu:
Won't Fix
Bug description:
A default install of cloud images on GCE results in a configuration of
NTP which will likely be problematic during leap seconds, because it
uses both Google's leap-smeared time source, and the public pool,
which uses true UTC. These should not be combined in the default
configuration.
The principle of least astonishment would suggest that a non-standard
feature like leap smearing should be disabled by default.
This behaviour has been consistent in the 3 different GCE regions in
which I've recently created instances.
