Golang proposal: time: Duration float scaling method

This is kinda annoying:

delay := time.Duration( float64(baseDelay) * backoffFactor )

It would be nicer if you could just do this:

delay := baseDelay.Scale(backoffFactor)

You could paste this in each package you were needing this:

func scaleDuration(d time.Duration, s float64) time.Duration {
    return time.Duration(float64(d) * s)
}

...but probably nicer built into time.Duration?

Have a good day :)

Since this is not a fundamental operation on durations, helpers like this fall in to the category of https://go.dev/doc/faq#x_in_std

Since this is not a fundamental operation on durations,

This is used quite common.
