Shifting a specific part of the graph

I have a graph with the time for x-axis and frequency for y-axis with 2 curves (A and B). The time is in milliseconds range.

I attached the table below from which I generated the graph. Curve A is from the table tt.xlsx. Curve B is from the table tt1.xlsx.

I want to shift the time range of curve A from '09:02:03.079' to '09:02:04.079' for 705 milliseconds forward. The thing is I don't want to shift the entire curve and I only want to shift the specific time I want with a specific value.

Can someone help me?

If I am understanding corrrect, You want to change (12:32:45.678 to 12:32:47.678) to (12:32:46.383 to 12:32:48.383)?

Also, it would be helpful if you can attach your data.

Yes, that's what I meant. I attached the data. And I change the time range a bit. Can you take a look?
