Example 1: How to Use Time.AppendFormat() Function
package main
import (
"fmt"
"time"
)
func main() {
// Define a specific date
date := time.Date(2023, 7, 1, 12, 0, 0, 0, time.UTC)
// Create a slice to append to
dest1 := []byte("Date in YYYY-MM-DD format: ")
dest2 := []byte("Date in DD/MM/YYYY format: ")
dest3 := []byte("Date in MM-DD-YYYY format: ")
// Format the date and append it to the slice
dest1 = date.AppendFormat(dest1, "2006-01-02")
dest2 = date.AppendFormat(dest2, "02/01/2006")
dest3 = date.AppendFormat(dest3, "01-02-2006")
fmt.Println(string(dest1))
fmt.Println(string(dest2))
fmt.Println(string(dest3))
}Output
Date in YYYY-MM-DD format: 2023-07-01
Date in DD/MM/YYYY format: 01/07/2023
Date in MM-DD-YYYY format: 07-01-2023
Example 2: Format the time and append it
package main
import (
"fmt"
"time"
)
func main() {
// Get the current time
now := time.Now()
// Create a slice to append to
dest := []byte("Current time: ")
// Format the time and append it to the slice
dest = now.AppendFormat(dest, "2006-01-02 15:04:05")
fmt.Println(string(dest))
}Output
Current time: 2023-07-01 21:37:43That’s it.
