Data delivery
  • Let |state:PressureState| be an [=adjusted pressure state=] given |data| and |source|.
  • Let |timestamp:DOMHighResTimeStamp| be a timestamp representing the time the |data| was
    obtained from the |relevantGlobal|'s [=platform collector=].
    The |data| sample and mapping between |data| sample, and [=pressure states=],
    is [=implementation-defined=] and may use many different metrics. For instance,
    for CPU, it might consider processor frequency and utilization, as well
    as thermal conditions.
  • Let |timestamp| be an platform-specific timestamp converted in an [=implementation-defined=]
    way to an [=monotonic clock/unsafe current time=] using the same [=monotonic clock=]
    that is shared by [=environment settings object/time origins=].
    The goal of this step is to ensure that a timestamp that may have been relative to
    a different time origin is converted to a value that can be used in computations with
    the same [=monotonic clock=] used by the operations described in [[HR-TIME]].
  • Let |timeValue| be the [=relative high resolution time=] based on |timestamp| and
    |relevantGlobal|.
  • [=list/For each=] |observer:PressureObserver| in |relevantGlobal|'s
    [=registered observer list=] for |source|:
