> The current logic to calculate the queue time of a ReplicationTask is as follows:
> {code:java}
> (Instant.now().getNano() - task.getQueued().getNano()) / 1_000_000; {code}
> But Instant's nano only records the nanosecond part, it's like operation of mod.
> For example, if nano part of getQueued is 500_000_000,  and queue time is 600ms
> {code:java}
> // code placeholder
> getQueued                500_000_000
> in Queue                    600_000_000
> getProcessed            1100_000_000
> call getNano()             100_000_000{code}
> Then the result of the code mentioned above would be (100_000_000 - 500_000_000) / 1_000_000, which is -400.
>  
> This ticket is to solve this bug by using Duration.between to get the correct queueTime.
