Can I know that in an issue who all have logged time?

[Ashish Pandey]

If i have created a subtask in story and in that subtask two different users have logged the time then can I come to know that how much time both users have logged in that subtask?

All the information is recorded on the issue, so you can find out if you want. But if you need a nice report, you need a plugin like Tempo.
