Duration.Round in Go

Round returns the result of rounding d to the nearest multiple of m. The rounding behavior for halfway values is to round away from zero. If the result exceeds the maximum (or minimum) value that can be stored in a Duration, Round returns the maximum (or minimum) duration. If m <= 0, Round returns d unchanged.

package main

import (
	"fmt"
	"time"
)

func main() {
	d, err := time.ParseDuration("1h15m30.918273645s")
	if err != nil {
		panic(err)
	}

	round := []time.Duration{
		time.Nanosecond,
		time.Microsecond,
		time.Millisecond,
		time.Second,
		2 * time.Second,
		time.Minute,
		10 * time.Minute,
		time.Hour,
	}

	for _, r := range round {
		fmt.Printf("d.Round(%6s) = %s\n", r, d.Round(r).String())
	}
}
