Golang : Comparing date or timestamp
Problem :
You have to compare two timestamps to see if the they are equal or not.
Solution :
Use time.Equal()
function to compare the timestamps. For example :
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("Today : ", now.Format("Mon, Jan 2, 2006 at 3:04pm"))
longTimeAgo := time.Date(2010, time.May, 18, 23, 0, 0, 0, time.UTC)
// compare time with time.Equal()
sameTime := longTimeAgo.Equal(now)
fmt.Println("longTimeAgo equals to now ? : ", sameTime)
// calculate the time different between today
// and long time ago
diff := now.Sub(longTimeAgo)
// convert diff to days
days := int(diff.Hours() / 24)
fmt.Printf("18th May 2010 was %d days ago \n", days)
}
Sample output :
./timecompare
Today : Wed, May 27, 2015 at 12:38am
longTimeAgo equals to now ? : false
18th May 2010 was 1834 days ago
