## What changes were proposed in this pull request?
The current logic to calculate the queue time of a ReplicationTask is as
follows:
```
(Instant.now().getNano() - task.getQueued().getNano()) / 1_000_000;
```
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
| item | time|
|---| ---|
|getQueued|500_000_000|
|in Queue|600_000_000|
|getProcessed|1100_000_000|
|call getNano()|100_000_000|
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.
