function parseDatetimeString(datetimeString) {
  const parts = datetimeString.split(/[\s,:]+/); // 使用空格、逗号和冒号作为分隔符
  const month = parseMonth(parts[0]);
  const day = parseInt(parts[1]);
  const year = parseInt(parts[2]);
  const timeParts = parts[3].split(":");
  const hour = parseInt(timeParts[0]);
  const minute = parseInt(timeParts[1]);
  const second = parseInt(timeParts[2]);
  
  return new Date(year, month, day, hour, minute, second);
}

function parseMonth(monthString) {
