[移动开发]kotlin 计算两个时间的秒差

import java.text.SimpleDateFormat
import java.util.*


fun main(args: Array<String>) {
    var dateFormat = SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
    val startTime = "2022-3-10 20:18:17"
    val endTime = "2022-11-30 15:15:17"

    var sTime: Date = dateFormat.parse(startTime)
    //var eTime: Date = dateFormat.parse(endTime)
    var eTime: Date = Calendar.getInstance().time//系统现在时间
    println("eTime=$eTime")
    val diff = eTime.time - sTime.time
    val days = diff / (1000 * 60 * 60 * 24)
    val hours = (diff - days * (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)
    val minutes = ((diff - days * (1000 * 3600 * 24)) - hours * (1000 * 3600)) / (1000 * 60)
    val second = (diff - days * 1000 * 3600 * 24 - hours * 1000 * 3600 - minutes * 1000 * 60) / 1000
    println("差距(秒): " + (diff / 1000))
    println("$days d $hours h $minutes m $second s")
