Just a test in Go to calculate the diff between dates

diff-dates.go

package main

import (
	"fmt"
	"time"
)

func main() {
	datetimeFormat := "2006-01-02 15:04:05"
	today, _ := time.Parse(datetimeFormat, "2017-04-16 23:00:00")
	fmt.Printf("%v\n", today)
	
	tomorrow, _ := time.Parse(datetimeFormat, "2017-04-17 00:00:00")
	fmt.Printf("%v\n\n", tomorrow)
	
	diff := today.Sub(tomorrow)
	fmt.Printf("%v\n", diff)
	fmt.Printf("%v\n", int(diff.Hours()))
	
}
