-- supported, at most @pTimeDomainCount@ values will be written to
-- @pTimeDomains@, and 'Vulkan.Core10.Enums.Result.INCOMPLETE' will be

-- | vkGetCalibratedTimestampsKHR - Query calibrated timestamps
--
-- = Description
--
-- The maximum deviation /may/ vary between calls to
-- 'getCalibratedTimestampsKHR' even for the same set of time domains due
-- to implementation and platform specific reasons. It is the application’s
-- responsibility to assess whether the returned maximum deviation makes
-- the timestamp values suitable for any particular purpose and /can/
-- choose to re-issue the timestamp calibration call pursuing a lower
-- 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
-- re-calibrate the timestamps on a regular basis.
