After meassuring the answer time of a software system I calculated the standard deviation from the samples. The average time is about 200ms, the standard deviation $$\sigma = 300ms$$ According to the image below this should mean that 68.2% of all response times should be between -100ms and 500ms.

A negative response time makes obviously no sense. How should the part of the normal distribution be interpreted that is enclosed in the red box?

Sample data with similiar avg ~202 stddev ~337:
