Fix Organization API From and To request options. Swap Unix() with UnixMilli()

[m1keru]

Atlassian API wants Epoch in milliseconds

I noticed during the debug that requests to the API go with Unix timestamp in seconds but Atlassian API wants milliseconds.

Here is the reference to their API:

Hi @m1keru, thank you for investing for time in this project.

Can you please review the test cases?, it seems the change broke them..
