public class TimestampCurrentTimeEventGenerationFilter
extends AbstractCurrentTimeEventGenerationFilter<java.lang.Long>

Generates time events with a given resolution based on the timestamps of incoming IMonitoringRecords.

1. The first record received immediately leads to a new TimestampRecord with the given timestamp.
2. The timestamp of the first record is stored as AbstractCurrentTimeEventGenerationFilter.firstTimestamp and future events are generated at AbstractCurrentTimeEventGenerationFilter.firstTimestamp + i * AbstractCurrentTimeEventGenerationFilter.timerResolution.
3. Future IMonitoringRecord may lead to future TimestampRecord as follows:
   1. A newly incoming IMonitoringRecord with logging timestamp tstamp leads to the new timer events satisfying AbstractCurrentTimeEventGenerationFilter.firstTimestamp + i * AbstractCurrentTimeEventGenerationFilter.timerResolution < tstamp.

It is guaranteed that the generated timestamps are in ascending order.
