How to do date/time comparison

Question

Is there any options in doing date comparison in Go? I have to sort data based on date and time - independently. So I might allow an object that occurs within a range of dat

Answer 1

For comparison between two times use time.Sub()

// utc life
loc, _ := time.LoadLocation("UTC")

// setup a start and end time
createdAt := time.Now().In(loc).Add(1 * time.Hour)
expiresAt := time.Now().In(loc).Add(4 * time.Hour)

// get the diff
diff := expiresAt.Sub(createdAt)
fmt.Printf("Lifespan is %+v", diff)

The program outputs:

Lifespan is 3h0m0s
