Managing time

The Go programming language’s time package provides two functions that allow you to manipulate time. One of them is called Sub(), and the other one is called Add(). There have not been many cases, in my experience, where this has been used. Mostly, when calculating the elapsed time of a script’s execution, the Sub() function is used to tell the difference.

Let’s see what the addition looks like:

  timeToManipulate := time.Now()
  toBeAdded := time.Duration(10 * time.Second)
  fmt.Println("The original time:", timeToManipulate)
  fmt.Printf("%v duration later %v", toBeAdded, timeToManipulate.Add(toBeAdded))

After execution, the following output welcomes us:

The original time: 2023-10-18 08:49:53.1499273 +0200 CEST m=+0.001994601
10s duration later: 2023-10-18 08:50:03.1499273 +0200 CEST m=+10.001994601

Let’s inspect what happened here. We created a variable to hold our...
