-- = Description
--
-- If @pTimeDomains@ is @NULL@, then the number of calibrateable time
-- domains supported for the given @physicalDevice@ is returned in

-- array, and on return the variable is overwritten with the number of
-- values actually written to @pTimeDomains@. If the value of
-- @pTimeDomainCount@ is less than the number of calibrateable time domains
-- supported, at most @pTimeDomainCount@ values will be written to
-- @pTimeDomains@, and 'Vulkan.Core10.Enums.Result.INCOMPLETE' will be
-- returned instead of 'Vulkan.Core10.Enums.Result.SUCCESS', to indicate
-- that not all the available time domains were returned.

-- deviation value.
--
-- Calibrated timestamp values /can/ be extrapolated to estimate future
-- coinciding timestamp values, however, depending on the nature of the
-- time domains and other properties of the platform extrapolating values
-- over a sufficiently long period of time /may/ no longer be accurate
-- enough to fit any particular purpose, so applications are expected to
