We changed some simple things in this simulation, such as pausing the simulation at exactly 70 days, as shown in the "Time since last initialization" field, and the Location and Contact information.
The "Pause" feature allows to precisely control sysUpTime, the MIB object which reflects running time of the device. You can even set it into the future, to test counter wrap problems, for example.
Any MIB object instance can be changed at runtime, so that you can determine precise behaviour of the device. More about that later...
