Something like python timedelta in golang

Question

I want to get a datetime, counting weeks from a date, days from a week and seconds from 00:00 time.

With Python I can use this:

BASE_TIME = datetime.datetime(1980,1,6,0,0) tdelta = datetime.timedelta(weeks = 1722,                             days = 1,                             seconds = 66355) mydate = BASE_DATE + tdelta 

I'm trying to get it with Go, but I have some problems to reach it:

package main  import (     "fmt"     "time" )  var base = time.Date(1980, 1, 6, 0, 0, 0, 0, time.UTC)  func main() {     weeks := 1722     days := 1     seconds := 66355     weeksToSecs := 7 * 24 * 60 * 60     daysToSecs := 24 * 60 * 60     totalSecs := (weeks * weeksToSecs) + (days * daysToSecs) + seconds     nanosecs := int64(totalSecs) * 1000000000      //delta := time.Date(0, 0, 0, 0, 0, totalSecs, 0, time.UTC)      date := base.Add(nanosecs)      fmt.Printf("Result: %s", date)  } 

prog.go:21: cannot use nanosecs (type int64) as type time.Duration in function argument

What I'm missing?
Thanks

package main  import (         "fmt"         "time" )  func main() {         baseTime := time.Date(1980, 1, 6, 0, 0, 0, 0, time.UTC)         date := baseTime.Add(1722*7*24*time.Hour + 24*time.Hour + 66355*time.Second)         fmt.Println(date) }
