CPU/GPU time calibration on OpenCL Trace Capture

When I capture "Process - OpenCL - OpenCL Trace" using Trace Capture, I can see the execution timeline in the "Trace 1" window. However, when I download the captured data from Data Explorer, CPU time is based on program start time and GPU time is based on system time (ex. CPU Start: 1,163,372us, GPU Start: 1,615,110,417,174,153us). To draw a timeline directly with downloaded capture data, CPU time and GPU time should be based on the same time, how can I calibrate it?

 

It is possible to calculate the difference between the program start time and the system time on the GUI, but I wonder if there is a better way.
