HarmonyOS 判断当前时间是否在一个时间段内

private fStartTime = "00:00:30"  
private fEndTime="00:59:59"  
  
let now = new Date();  
let fStartTimeDate = new Date(`${now.getFullYear()}-${now.getMonth() + 1}-${now.getDate()} ${this.fStartTime}`).getTime();  
let fEndTimeDate = new Date(`${now.getFullYear()}-${now.getMonth() + 1}-${now.getDate()} ${this.fEndTime}`).getTime();  
console.info(`开始区间：${fStartTimeDate}`)  
console.info(`结束区间：${fEndTimeDate}`)  
console.info(`现在时间：${now.getTime()}`)
