Author: Ice Scripter

How to use the program:
    use the "get_remaining_time" function and put your time that you would like to count down to in the "()"

Default time is set to 1559148288 + 604800
]]--

local countdown_time = 1559148288 + 604800-- Time it counts down from --
local time_math -- Creating a nil variable for future use

local function get_remaining_time(x)
    if x ~= nil then -- if x isn't nil it will replate time_math with x - os.time() --
        time_math = x - os.time()
    else
        time_math = countdown_time - os.time()
    end
    
    print("Getting remaining time...")
    
    if countdown_time > os.time() then
        return math.floor (time_math /60 /60 /24 %7) .. ":" .. math.floor (time_math /60 /60 %24) .. ":".. math.floor (time_math /60 % 60) .. ":" .. math.floor (time_math %60) -- Returns this if time is still remaining. --
    else
        return "Countdown complete." -- Returns this when the countdown is completed --
    end
end

print(get_remaining_time().."\n") -- prints the time left --
print("Current time in seconds: ".. os.time().. "\nCount down time: "..countdown_time) -- Prints the current time and countdown time (in seconds) --
