Simple time tracker page

Hi!

I need a simple time tracker.

Please see this mockup, before/instead reading : https://balsamiq.cloud/swfpll8/pvqtsfo (or in attachement)

DeadLine - somewhere in next week - 17.05.2018 15:00 CEST.


Configuration part:
1. "Task" list - I need option to create tasks. Task has only ID, Shortcut, Name and Multiplier field for now. For example:

1, OffPrep, Offer preparation, 1
2, RepPrep, Report preparation, 1,5


I should also see all Users from user list and be able to tick them (enable them for this particular task)


2. User list - I need option to add users, there are, three user levels, Admin, Manager, User
User - can use TimeTracker option only
Manager - can use TimeTracker, and: add new "Tasks" to the list, and add Users but only User level
Admin - can use TimeTracker, and add "Tasks" and Users

For user i need ID, Login, Name, Password, Level, Description, LastSeen

I should also see all "tasks" from "task" list and be able to tick them (enable them for this particular user)
For Manager level user, I should also see all Users from user list and be able to tick them (bind them with this particular Manager)

3. Usage
User is logging to the system, if he is plain User, he see only two tabs TimeTracker and Report

TimeTracker is the page that is loaded after logging in, he sees drop-down list with "TaskList" that has been enabled for him, the "notes" field and start button.

Starting selected task is actually only save:
ID, user ID, task ID, Start_timestamp, Stop_timestamp, description/notes

It will be nice if we can display counter with time elapsed from pressing Start button

When user logs in second time, he sees (counter) and Stop button, when he push Stop, I need timestamp in Stop_timestamp field


Then Manager or Admin logs in
They see TimeTracker, Reports, Users list and "Task" list

Reports is basically history
User can see His log day by day in full details or Task list with, sum, min, max, avg time for each task
Manager and Admin can see the same reports as user but, he can choose one or more (also all) his users and data will be computed
