Adding onto @Dolphin_Worms, you can put that value through the function below to get it in HH:MM:SS format.

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

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