Sub returns the duration t-u. If the result exceeds the maximum (or minimum) value that can be stored in a Duration, the maximum (or minimum) duration will be returned. To compute t-d for a duration d, use t.Add(-d).

package main

import (
	"fmt"
	"time"
)

func main() {
	start := time.Date(2000, 1, 1, 0, 0, 0, 0, time.UTC)
	end := time.Date(2000, 1, 1, 12, 0, 0, 0, time.UTC)

	difference := end.Sub(start)
	fmt.Printf("difference = %v\n", difference)
}
