used across this interface.
MediumTimeElapsed
Number of seconds, including partial seconds, that
have elapsed since the beginning of the current
measurement period. If, for some reason, such as
an adjustment in the system’s time-of-day clock, the
current interval exceeds the maximum value, the
agent will return the maximum value.
