I want to convert a number to be formated as days:hours:minutes

function Format(Int)
    return string.format("%02i", Int)
end

function convert(Seconds)
    local Minutes = (Seconds - Seconds%60)/60
    Seconds = Seconds - Minutes*60
    local Hours = (Minutes - Minutes%60)/60
    Minutes = Minutes - Hours*60
    local Days = (Hours - Hours%24)/24
    Hours = Hours - Days*24
    return Format(Days)..":"..Format(Hours)..":"..Format(Minutes)
end

convert(500)

However, no matter what number I enter, I always get 00:00:00 back

function Format(Int)
    return string.format("%02i", Int)
end

function convert(seconds)
    local Minutes = math.floor(seconds/60)
    local Hours = math.floor(Minutes/60)
    Minutes = Minutes - Hours*60
    local Days = math.floor(Hours/24)
    Hours = Hours - Days*24

    return Format(Days)..":"..Format(Hours)..":"..Format(Minutes)
end

print(convert(86400))

This seems to work for me. I only just wrote it up, but it should work fine!

 local Minutes = math.floor(seconds/60)
 seconds = seconds % 60
 local Hours = math.floor(Minutes/60)
 Minutes = Minutes%60
 local Days = math.floor(Hours/24)
 Hours = Hours%24
 
 return (Format(Days)..":"..Format(Hours)..":"..Format(Minutes))

There you go.

local function divmod(x, y) return x / y, x % y; end;
local Days, Hours, Minutes, Seconds;
Minutes, Seconds = divmod(Seconds, 60);
Hours, Minutes = divmod(Minutes, 60);
Days, Hours = divmod(Hours, 24);
return Format(Days)..":"..Format(Hours)..":"..Format(Minutes);

I have a function where you simply put the number in a parameter of a function. Ill edit this post in a minute with the function

local function ToHMS(s)
  return ("%02i:%02i:%02i"):format(s/60^2,s/60%60,s%60)
end

print(ToHms(500))

Try printing out the Days, Hours and Minutes to see does it print 0 just in case, because it works when I tried it.

Is there any particular reason you need your own function?

local seconds = 120320
os.date('!%H:%M:%S', seconds) --09:25:20

Isn’t the question convert number to days:hour:minutes or am I mistaken? That is hours:minutes:seconds not days:hours:minutes.

#12 
os.date('!%d:%H:%M', 1600000) --20:06:13

EDIT: I should note this only works for seconds below 2678400. For cases above that you can use one of the solutions above or make os.date also display the month.
