UTC时间转北京时间

fun main() {
    val formatPattern = "yyyy-MM-dd HH:mm:ss"
    val utc = "2019-07-10T16:00:00.000Z"
    val time = parse(utc, formatPattern)
    println(time)
}

fun parse(utc: String, formatPattern: String): String {
    val zdt = ZonedDateTime.parse(utc)
    val ldt = zdt.toLocalDateTime()
    val formatter = DateTimeFormatter.ofPattern(formatPattern)
    return formatter.format(ldt.plusHours(8))
}
