格式化时间为MM:SS，即使它不是完整的分钟

function formatTime(seconds) {
  var date = new Date(null);
  date.setSeconds(seconds);
  var minutes = date.getUTCMinutes();
  var seconds = date.getSeconds();
  return minutes.toString().padStart(2, '0') + ':' + seconds.toString().padStart(2, '0');
}

var timeInSeconds = 150;
var formattedTime = formatTime(timeInSeconds);
console.log(formattedTime); // 输出：02:30

from datetime import datetime, timedelta

def format_time(seconds):
    time = timedelta(seconds=seconds)
    minutes = (time.seconds // 60) % 60
    seconds = time.seconds % 60
    return '{:02d}:{:02d}'.format(minutes, seconds)

time_in_seconds = 150
formatted_time = format_time(time_in_seconds)
print(formatted_time)  # 输出：02:30
