When doing a spares latency check, it is required to know if a latency
object was started.
This returns true if the start timer was set.

The latency object is used to simplify calculating latencies. It uses a
start and stop time_point so the latency can be queried multiple time.
The start need to be done explicitely and not in the constructor to
allow reuse of the object.
