How to convert between timezones in Go?

Question

For example time.Now() has a timezone of UTC.

utcNow := time.Now()
fmt.Println(utcNow)

Outputs

2009-11-10 23:00:00 +0000 UTC

How do I convert this time to Japan Standard time?

It looks like you're running that in the Go playground, which is why the time is automatically set to UTC (it's also always set to November 2009 when a program is launched).

If you run time.Now() on your own machine, it should pick up the local region. Alternatively, if you want to force the time to be in a specific timezone, you can use a time.Location object along with the time.Time.In function.

l, err := time.LoadLocation("Asia/Tokyo") // Look up a location by it's IANA name.
if err != nil {
    panic(err) // You can handle this gracefully.
}
fmt.Println(utcNow.In(l))

Note that it's still showing the same moment in time, but now with JST's offset.

For more information, look at the go documentation for the time package. http://golang.org/pkg/time

How do you print the time in another timezone. I.e show a server generated time to the user in their timezone – TheRealChx101 Jul 09 '22 at 19:35
