Change time tracking measurement

Question

Hey guys! 
Could you, please, help me find a place where I can change time tracking measurement?

I need to track time in days/hours/minutes. In my Jira, I can choose the date only. In the admin setting, I can find the date selector, and I can't find time selector.

Does anybody know how to add this?

Thank you in advance!

Thank you, Nic! It seems I have managed this issue.

You need to adjust the screens for each project so that it includes the time-tracking fields.  Hopefully, they are using shared screens so you don't need ot change a lot of them.

Thank you very much, Nic!

I have advanced in this issue a little bit. 
I have managed to set original time estimation that counts in days/hours/minutes since I have admin access.

The following issue is how to change time estimation in existing projects. When I create a new issue, I can fill the field as I need. But I can't set up estimation to existing projects.
