[SNMP4J] Engine boots and engine time

[Jochen Katz]

Hi,

you have to increase the engine boot value with each start of your
application/device.

> I am not setting any explicit value for engine time.

The time is the amount of seconds since the last increase of the engine
boots value. So this has to be the uptime of the application/device in
seconds.

This is the expected behaviour if wrong values are used.
