Please answer the following before submitting your issue:

1. What version of Delve are you using (dlv version)? 1.20.2
2. What version of Go are you using? (go version)? go version go1.20.3 darwin/arm64
3. What operating system and processor architecture are you using? ARM64
4. What did you do? Use go trace
5. What did you expect to see? output with timestamp
6. What did you see instead?

It would be great to add timestamp in the trace output so that the users can sync the function call with the application log or other external source.

For example, the current output is:

> goroutine(1967): ...

We can add a timestamp at the beginning of each line like:

2023-05-05 12:00:00.123 > goroutine(1967): ...

Some trace tools like strace have several options to enable timestamp, which is quite helpful.

I could submit a PR for it if this feature is accepted.

I think it's fine to do but it should be behind a flag.
