Get the current time and the time one year later (China Standard Time) time processing

get current time

/**
 * 获取当前时间
 * @param timeStr 时分秒 字符串 格式为 xx:xx:xx
 */
export function getNowDateTime(timeStr) {
  let now = new Date();
  let year = now.getFullYear(); //得到年份
  let month = (now.getMonth() + 1).toString().padStart(2, "0"); //得到月份
  let day = now.getDate().toString().padStart(2, "0"); //得到日期

  if (timeStr == undefined) {
    return `${year}-${month}-${day}`;
  }

  let seconds = now.getSeconds().toString().padStart(2, "0") // 得到秒;
  return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
}
