In Taskulu, there are two ways for you to add your timelogs.
One way is to activate log time and let the system automatically save your working hours .
you could find more about it from the link below
The other way is to add your times manually from the project's "Timelogs" section.
To open the page, click on Timelogs icon in the project sidebar.
You need to add the task, a description about the task and the date and time .
You can only choose from the tasks you have been assigned to. If you are the project owner, first you need to assign the tasks to yourself.
( A shortcut for that is to keep the mouse on it and press space bar)
Please notice that timelogs are for tasks you have worked on in the past , so you can not add dates and times for the future
If you forgot to log your time
You can add timelogs manually as you see in the gif below:
