If
you want to view profiling information, you should enable either timestamping
or cycle accurate tracing, or both. Better results in profiling are generally
obtained with timestamping enabled. Enable Timestamping
Selecting Enable Timestamping enables the timestamp recording logic in the trace capture hardware. Timestamps are displayed in the Time/unit and +Time columns of the Analysis window. You can change the format in which timestamps are displayed using the Scale Time Units option in the View menu. Analyzing timestamp values enables you to see, for example, when pauses have occurred in processor execution, and how long it takes between successive invocations of a particular section of code.

Not all types of trace capture hardware support this feature. Refer to your hardware documentation for more information.
Transmitting
the timestamps uses noticeable additional bandwidth on the trace capture
hardware to host connection. Storing the timestamps in the trace capture
hardware might reduce the maximum length of trace that you can capture.
You should therefore only enable this feature when you have to.
