How can i make the game time change?

i got 2 text boxes, one for hours and one for minutes

how can i make it so the in game minutes is the same as the textbox for minutes text and in game hours is the same as the textbox for hours? local script:

script.Parent.MouseButton1Click:Connect(function()
local hour = tonumber(script.Parent.Parent.hour.Text)
local minute = tonumber(script.Parent.Parent.minutes.Text)
game.ReplicatedStorage["control time"]:FireServer(hour,minute)
end)

server script:

local minutes = 60 * 12
game.ReplicatedStorage["control time"].OnServerEvent:Connect(function(plr,hour,minute)
    minutes = minute * hour
end)
while true do
    game.Lighting:SetMinutesAfterMidnight(minutes)
    minutes = minutes + 1
    print(minutes)
    if game.Lighting.ClockTime == 12 then
        game.ServerStorage.day.Parent = game.Lighting
        game.Lighting.night.Parent = game.ServerStorage
    end
    if game.Lighting.ClockTime == 18 then
        game.Lighting.day.Parent = game.ServerStorage
        game.ServerStorage.night.Parent = game.Lighting
    end
    wait(1.5)
end
