public class TickingTimeSource extends java.lang.Object implements TimeSource, Service
TimeSource that increases the time in background using a timer. This time usually gives better performances
to Ehcache than the default SystemTimeSource. However, it will create a background thread that will continuously
wake up to update the time.
It works be increasing the time at a given granularity. So if you set the granularity at 10ms, a timer is called every 10ms and will increase the current time of 10ms. This will cause the current time to diverge a bit from the system time after a while. So you specify a system update period where the current time will be reset to the system time.

ServiceServiceProvider.
The service provider allows a service to retrieve and use other services.
A Service retrieved at this stage may not yet be started. The recommended usage pattern therefore, is to keep a
reference to the dependent Service but use it only when specific methods are invoked on subtypes.
