When Now is not the time (in Go)

#go

When testing two time.Time variables for equality in Go, you may find that there are (ahem) times when you get surprising results if you don't use time.Equal():

package main

import (
    "fmt"
    "time"
)

func main() {

    now := time.Now()
    nowUTC := now.UTC()

    fmt.Println("now:   ", now.Location(), now.Format("15:04"))
    fmt.Println("nowUTC:", nowUTC.Location(), " ", nowUTC.Format("15:04"))
    fmt.Println("-----")

    fmt.Printf("now == nowUTC:     %t\n", now == nowUTC)

    fmt.Printf("now.Equal(nowUTC): %t\n", now.Equal(nowUTC))

}

// Output:
// now:    Local 23:00
// nowUTC: UTC   23:00
// -----
// now == nowUTC:     false
// now.Equal(nowUTC): true
