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.
Procedure
After you run tests with resource monitoring or response time breakdown enabled, follow these steps to correct the time offset:
- In the Test Runs view, right-click the host where you want 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 you want to use, and click OK.
Results
The response time breakdown and resource monitoring data on the selected host displays with a corrected time offset.
