# Log time on tasks

Record the time you spend, from a task's Timesheets tab or from the Timesheets app, follow the time left on a task, and know which lines are written for you.

A timesheet line says that one employee spent some time, on a date, on a task of a project. You write it where you work: on the task itself, or in the **Timesheets** app, which lists every line you wrote.

## Before you start {#before-you-start}

- You need an access right on **Timesheets** and an employee linked to your user in the current company ([Employees](/docs/employees)); without one, saving a line fails with "Timesheets must be created with an active employee in the selected companies."
- The project must have **Timesheets** ticked: in the window that creates it, or later under **Time Management** in its **Settings** tab.
- A line belongs to a project; a task without a project, a private to-do, takes no time.

## From the task {#from-the-task}

Open the task, then its **Timesheets** tab, click **Add a line** and fill **Description** and **Time Spent**; the date is today and the employee is you. [Your first project](your-first-project#log-time) goes through it step by step. Under the lines, the task adds up **Time Spent**, and **Time Remaining** when an **Allocated Time** is set; the percentage next to **Allocated Time** follows. Time logged on sub-tasks counts in the parent task too.

When the time spent passes the time allocated, the remaining time turns negative and red on the card. In the projects list, the **Timesheets >100%** filter shows the projects in that case.

## From the Timesheets app {#from-the-app}

1. Open **Timesheets/Timesheets/My Timesheets**. The list holds your own lines, the newest first.
2. Click **New**. A line opens at the top, dated today, on the project you used most in your last lines (the company's internal project before your first line).
3. Choose the **Project**, then the **Task**, type the **Description** and the **Time Spent**, here `01:30` on the task Unit Testing of Research & Development.

4. Click **Save**.

The same line appears in the task's **Timesheets** tab. The buttons at the top right show your lines as a calendar, cards, a pivot table or a chart.

Time is typed in hours and minutes, `01:30`, unless the settings record it in days: [Projects and timesheets settings](projects-settings).

## Lines written for you {#automatic-lines}

With the **Time Off** option of the settings, each validated time off and each public holiday writes lines on the internal project, task **Time Off**, for the hours of your working schedule ([Time off](/docs/time-off)). The time logged on legal cases and consultations goes through **Case Timesheets** and **Consulting Timesheets** in the same app ([Cases](/docs/law-cases)).

## See everybody's time {#all-timesheets}

With **User: all timesheets** on **Timesheets**, **Timesheets/Timesheets/All Timesheets** lists the lines of every employee in the projects you can see, and the reports of [Review time and progress](review-time-and-progress) open.

## FAQ {#faq}

### My project is not in the Project list of a new line. {#project-missing}

Its **Timesheets** option is off, it is archived or a template, or its visibility keeps you out.

### Can I log time for a colleague? {#for-a-colleague}

Only with **User: all timesheets** or more, by choosing the colleague in **Employee** on the task's **Timesheets** tab. With **User: own timesheets only**, every line is yours.

### I cannot delete a task. {#delete-task}

A task with timesheet lines cannot be deleted. Delete its lines first, or archive the task.

### Does logged time need an approval? {#approval}

No. A line counts as soon as it is saved; anyone allowed to see it can still change it.
