Add tokio version of std::fs::File::set_times

[arpankapoor]

Is your feature request related to a problem? Please describe.
Need async functions to set file times.

Describe the solution you'd like
Add tokio versions of std::fs::File::set_times and std::fs::File::set_modified.

Describe alternatives you've considered
Either reopen the file using std::fs::File and use set_times or use the filetime crate on the path.

Additional context
The std versions were introduced in 1.75 and I see that the current tokio MSRV is 1.63. I'm guessing using something like rustversion for conditional compilation would be a no go? Is there any other way to add this besides waiting until the MSRV reaches 1.75?

You can implement it yourself:

let std_file = file.into_std().await;
let file = tokio::task::spawn_blocking(move || {
    std_file.set_times(...)?;
    Ok(tokio::fs::File::from_std(std_file))
})??;

We'd rather not add this right now for the reasons you mentioned.
