Question

以下倒计时时钟的工作时间为秒，分钟，天，月，年，我将如何为此添加毫秒？

local secondsLeft = 3.154e + 7
-- one year


local clockText = display.newText("00.00:00:00:00", display.contentCenterX, 80, "font1.ttf", 60)



sceneGroup:insert(bg)
sceneGroup:insert(title)
sceneGroup:insert(summary)
sceneGroup:insert(clockText)



sceneGroup:insert(clockText)
local SECONDS_IN_HOUR = 60 * 60
local SECONDS_IN_DAY = 24 * SECONDS_IN_HOUR
local SECONDS_IN_MONTH = 30 * SECONDS_IN_DAY
-- assuming an average of 30 days per month
local SECONDS_IN_YEAR = 365 * SECONDS_IN_DAY

local function updateTime()
  -- decrement the number of seconds

  secondsLeft = secondsLeft - 1


  -- time is tracked in seconds.  We need to convert it to minutes and seconds


  local years = math.floor((secondsLeft / SECONDS_IN_YEAR) % 365)
  local months = math.floor((secondsLeft / SECONDS_IN_MONTH) % 12)
  local days = math.floor((secondsLeft / SECONDS_IN_DAY) % 30)
  local hours = math.floor((secondsLeft / SECONDS_IN_HOUR) % 24)
  local minutes = math.floor((secondsLeft / 60) % 60)
  local seconds = secondsLeft % 60




  -- make it a string using string format.
  local timeDisplay = string.format("%02d·%02d·%02d·%02d·%02d·%02d", years, months, days, hours, minutes, seconds)
  clockText.text = timeDisplay
end
local countDownTimer = timer.performWithDelay(100, updateTime, secondsLeft)
