You can use the module "time" to deal with time and date in Golang.
The Package time provides functionality for measuring and displaying time: calendrical calculations always assume a Gregorian calendar, with no leap seconds.
To load the time module you can do this:
import (
"fmt"
"time"
)
The example below shows the day given a date and formats two dates.
package main
import (
"fmt"
"time"
)
func days(year int, month time.Month) int {
return time.Date(year, month+1, 0, 0, 0, 0, 0, time.UTC).Day()
}
func main() {
fmt.Println(days(2019, 2)) // 28
fmt.Printf("%v", time.Date(2019, 3, 0, 0, 0, 0, 0, time.UTC)) // 2019-02-28 00:00:00 +0000 UTC
fmt.Println()
fmt.Printf("%v", time.Now().Format("2006-01-02 15:04:05"))
}
To get the elapsed time (while your program ran), try this code:
package main
import (
"fmt"
"time"
)
func main() {
startTime := time.Now()
time.Sleep(1 * time.Second)
elapsed := time.Since(startTime)
fmt.Printf("elapsed %v", elapsed) // elapsed 1.0005049s
}
