table.sort isn't sorting correctly! Why?

Why is this not working?

local TimeTable = {
	Day = {
		Calculated = 0,
		Seconds = 86400
	},
	Hour = {
		Calculated = 0,
		Seconds = 3600
	},
	Minute = {
		Calculated = 0,
		Seconds = 60
	},
	Second = {
		Calculated = 0,
		Seconds = 1
	}
}
table.sort(TimeTable,function(one,two)  return one.Seconds < two.Seconds end)
local SecondsAvailable = 86400

for i,v in pairs (TimeTable) do
	v.Calculated = math.floor(SecondsAvailable/v.Seconds)
	SecondsAvailable = SecondsAvailable - (v.Calculated*v.Seconds)
	print(i,":",v.Calculated)
end

OUTPUT:

Hour : 24
Minute : 0
Day : 0
Second : 0

But it Should be like:

Day : 1
Hour : 0
Minute : 0
Second : 0
