Hi Saman,

I'm not really sure what you time you are trying to get.

You can use the Clock_getTicks to see a simple timestamp. There is the xdc/runtime/Timestamp module also if you need finer granularity.
There is the ti/sysbios/hal/Seconds module if you need time of day.

Thanks for your response.
I want to know how much time is spent on my main task.
what about UIA analyzer?

You can enable Task load measuring. I would enable Swi and Hwi load measuring to get the most accurate measurements.

You can look at this thread for how to set it up. Note: you can get the load once Load is enable via
1. runtime APIs
2. ROV Tool in CCS
3. System Analyzer

The easiest of these is #2.
