Correcting time offset
Response time breakdown and resource monitoring data is time stamped using the system clock of the host computer. If there are differences between the system clocks of the host computers that you include in a test, then response time breakdown and resource monitoring data are skewed in reports. The best practice is to synchronize the system clocks on all computers that you include in a test. When this is not possible, you can correct the time offset of each host computer after a test run. Typically, correct the time offset on all computers to match the system clock of the workbench computer. After you run tests with resource monitoring or response time breakdown enabled, perform the following steps to correct the time offset:
- In the Test Runs view, right-click the host where to correct the time offset; then click...
Correct Time Offset
- Select a Shift Direction of positive or negative.
A positive shift moves the response time breakdown and resource monitoring data on the selected host to the right. A negative shift moves the response time breakdown and resource monitoring data on the selected host to the left.
- Type the hours, minutes, or seconds of the time offset to use, and click OK.
Results
The response time breakdown and resource monitoring data on the selected host displays with a corrected time offset.
