    Yonghao,

    In $skew, if there is a timestamp event and then a series of timecheck
    events after expiration of the time limit, a violation is reported on
    each such timecheck event.

    If a timecheck event occurs before expiration of the time limit,
    a violation is not reported.

    What happens if there is a series of timecheck events, one or more
    before expiration of the time limit and one or more after the time limit.

    Does $skew turn dormant after a timecheck event within the time limit,
    or does it continue to check each timecheck event which follows the
    timestamp event, even if there was a timecheck event before the time
    limit expires?

    The LRM implies that $skew remains active even after a timecheck event
    within the time limit ("$skew shall report timing violations for all data
    events occurring beyond the limit after a reference event."), but I am
    not sure that was the intent.

    Presumably, $timeskew in event based mode with remain active flag set
    would work the same way.

    $fullcheck is different in any case, though.

    Thanks,
    Shalom
