This read-write INTEGER is the time window, in seconds, over which the kxifThreshold error count is evaluated, and setting it to zero disables the associated alarm entirely. It matters because a raw error count is meaningless without a time base, so this object defines the sampling period used to decide if the threshold has been exceeded. An administrator troubleshooting intermittent port errors might shorten kxifThresholdTime to get faster alarm notification instead of waiting through a long averaging window.
