Stopwatch
A stopwatch is a timing instrument to time things such as races. You start it when something starts, and stop when it ends. It shows an elapsed time between start and end. Stopwatches count the time up from a particular moment. In this respect, they are different from
countdown timers that count the time down. Here is an example stopwatch that shows sailing around the world time.

Select Type of New Object dialog.

Creating a stopwatch using World Clock Preferences
Configuring Stopwatch
When you create a new stopwatch, a new node is created in Preferences. It may look like this:

New stopwatch settings in World Clock Preferences
The options here are:
- Location - defines time zone for stopwatch when its "Start date and time" is set.
- Label - stopwatch label (displayed on stopwatch).
- Start date and time - optional field that determines when stopwatch starts running. When not set, you can start stopwatch at any time manually.
- Action on double-click - determines what happens when stopwatch is double-clicked.
- Show this stopwatch - taskbar / desktop switch for stopwatch location.
Stopwatch Time Formats
Stopwatches can print time in different ways. How exactly? You can configure it on the
Time and date display options subnode.

Built in stopwatch time formats in World Clock Preferences
Stopwatch Format Examples
- %D %Dn %h %hn %m %mn - %D days %h hours %m minutes

Stopwatch using "%D %Dn %h %hn %m %mn" time format
- \n%D %Dn %h %hn - %D days %h hours on a new line

Stopwatch using "\n%D %Dn %h %hn" time format
- \n%D %Dn %02h:%02m:%02s - %D days HH:mm:ss on a new line

Stopwatch using "\n%D %Dn %02h:%02m:%02s" time format
See
countdown timers for a detailed description of all available time formatters.
Starting and Stopping Stopwatches
To control stopwatch, put mouse pointer over black triangle. When you do it, stopwatch control panel appears. In the screenshot below, you see Pause button that allows you to pause the stopwatch.

Pause button in stopwatch control panel
A paused stopwatch will instead show Run button on its control panel, as on the screenshot below. It resumes stopwatch.

Run button in stopwatch control panel
Stopwatch control panel on screenshots above consists of only one button: either Pause or Run, depending on stopwatch state. That's because we used a stopwatch example that counts time from a specific time moment.
If there is no stopwatch starting point, we get another variation of stopwatch that can be started, stopped, or reset at any time. For this kind of stopwatch we get another button in control panel - Reset. It sets stopwatch reading to zero.
