Elapsed Time Counter
Queries the total operation time in hours. Internally, each monitor is equipped with
a software counter, which counts the full number of operation hours. The counter
value is limited to 298261, which is equivalent to approximately 34 years of opera-
tion time. After this time, each monitor returns always the maximum value. The
counter is incremented only, if the monitor was powered on one full hour without
interruption. If the monitor is powered off prior one full hour, the counter will re-
main at its last value.
