The issue is a part of #284 which appears when we try to enqueue jobs with a difference of less than 1 second at a very high-rate. The exact issue happens since the enqueue methods convert the millisecond timestamp into seconds, thereby rounding off a large portion of the timestamp, which then means that conflicts appear if a similar job is scheduled before the first one is picked up by a worker.
