HarmonyOS 如何获得某个时区的时间并且转化成对应的格式

通过new Date()获取的默认时区就是GMT，ArkTS是基于ts的，对于时间处理是一样的，参考:

let nowDate = new Date();
console.log('nowDate----',nowDate)
console.log('year ----',nowDate.getFullYear())
console.log('month ----',nowDate.getMonth()+1)
console.log('date ----',nowDate.getDate())
console.log('hours ----',nowDate.getHours())
console.log('minute ----',nowDate.getMinutes())
console.log('second ----',nowDate.getSeconds())
