Here is what Timer looks like when you launch it.

When you press the Start button, the start time is recorded in two places, in the small window at the top, and in the main activity window.

Every time you press the Capture button, a split time is recorded.

If you pause the Timer, then no Elapsed time is recorded until you resume the Timer.

The Paused time and Resumed time are both recorded.

When you press the Finished button, the final time is recorded.

Using a file editor such as Notepad, here is what the file looks like...

You can adjust how the Timer window looks by using the Tools Menu. In here you can adjust the 3 fonts used, as well as how the columns of data are formatted. By using tabs, you can import your final Timer file into a spreadsheet. By not using tabs, the columns are space separated for a cleaner look in a regular text editor.
