public class UniqueTimeStampGenerator
extends Object

Utility class to generate unique date for market events. The problem is that some feed sources do not supply milliseconds (Opentick's) in the date field. Since AQ code depends on date to be unique within the type and feed source, we need to fake millisecond part. This object generates unique date by catching duplicates and assigning milliseconds sequentially.
Optionally, it is possible to generate a timestamp from a number like the number of milliseconds since unix epoch start.
