It is capable of thoroughly (including milliseconds) keeping track of the time spent on each task.
The information displayed contains details such as the name of the program that was used, the first and last time it was used, and the time spent using it.
For programs like web browsers, it can track the time that a user spent on a certain website, with a word processor, the document they spent the most amount of time on, etc.
In addition, it supports Unicode, which is why it will display the name of all the files, documents, and locations, as strange as they may be.
That being said, you will have to manually update the application using F5 to see the latest tasks performed.
