Time.Equal in Go

Equal reports whether t and u represent the same time instant. Two times can be equal even if they are in different locations. For example, 6:00 +0200 CEST and 4:00 UTC are Equal. See the documentation on the Time type for the pitfalls of using == with Time values; most code should use Equal instead.

package main

import (
	"fmt"
	"time"
)

func main() {
	secondsEastOfUTC := int((8 * time.Hour).Seconds())
	beijing := time.FixedZone("Beijing Time", secondsEastOfUTC)

	// Unlike the equal operator, Equal is aware that d1 and d2 are the
	// same instant but in different time zones.
	d1 := time.Date(2000, 2, 1, 12, 30, 0, 0, time.UTC)
	d2 := time.Date(2000, 2, 1, 20, 30, 0, 0, beijing)

	datesEqualUsingEqualOperator := d1 == d2
	datesEqualUsingFunction := d1.Equal(d2)

	fmt.Printf("datesEqualUsingEqualOperator = %v\n", datesEqualUsingEqualOperator)
	fmt.Printf("datesEqualUsingFunction = %v\n", datesEqualUsingFunction)
}
