Time converting problem?

Hi guys!

function DigitalTime(TimeNum)
local Time = math.max(0, TimeNum)
local minutes = math.floor(Time / 60) % 60
local seconds = math.floor(Time) % 60
local m = math.floor(Time)
local Timestring = string.format("d:d:d", minutes, seconds, m) 
return Timestring
end

print(DigitalTime(16.11231231238))

NOTE: d:d:d should actually be *02d:02d:03d" with a percentage sign before each of these - for some reason the website wouldn't let me put it like that :/

I have this function which converts this time to: 00:16:016

Any ideas why it is converts it to "016" when it should actually be "112"?

I have tried many different variations of this script and still get the same conversion :(

Is there a way to fix it and still keep the 3 numbers after the decimal place?

Any help appreciated! Thanks!
