Question: How to remove the start offset when combining traces?

[ghost]

Usually you combine traces from the same parallel execution run.
For comparison it could be useful to see different sequential runs below each other without a start offset.
How can I start every trace at 0 seconds with viztracer --combine?

Currently it's not possible to do this(directly with VizTracer). Synchronizing traces from different run might be a useful feature. I'll see how I could proceed on this.

You can also change the timestamp of the json file by yourself(or even write a plugin for it) if you need this feature asap.

Hi @kllp , I added the feature in master so you can combine reports with --align_combine and all the reports will be aligned from the start. I probably won't release it immediately, so you can install from git pip install git+https://github.com/gaogaotiantian/viztracer. Let me know if this works for you.

It works! Thank you so much @gaogaotiantian! You made my day!
