Mastering Go - Second Edition

Parsing dates

The name of the Go program that will be developed in this subsection is parseDate.go and it will be presented in two parts.

The first part of parseDate.go is next:

package main 
 
import ( 
    "fmt" 
    "os" 
    "path/filepath" 
    "time" 
) 
 
func main() { 
 
    var myDate string 
    if len(os.Args) != 2 { 
        fmt.Printf("usage: %s string\n",  filepath.Base(os.Args[0])) 
        return 
    } 
 
    myDate = os.Args[1] 

The second part of parseDate.go contains the following Go code:

    d, err := time.Parse("02 January 2006", myDate) 
    if err == nil { 
        fmt.Println("Full:", d) 
        fmt.Println("Time:", d.Day(), d.Month(), d.Year()) 
    } else { 
        fmt.Println(err) 
    } 
} 

If there is a character such as - between the name of the month and the year, you can use "02 January-2006" instead of "02 January ...
