Golangでローカル時間とUTC。あとstrptime()

tz2.go

package main

import (
        "fmt"
        "time"
)

func main() {
        TF := `2006-01-02 15:04:05.999 -0700`

        t := time.Unix(0, 0)
        fmt.Printf("localtime: %s\n", t.Format(TF))
        fmt.Printf("UTC:       %s\n", t.In(time.UTC).Format(TF))
}
