How can I get the current time and date in real life?

You can put something in serverscriptservice called time and put this inside of it.

local TimeServer = "http://www.timeapi.org/utc/now?%25Q"
local CurrentTime = tonumber(Game:GetService("HttpService"):GetAsync(TimeServer, true))
local ServerTime = tick()

return function() return (CurrentTime / 1000) - ServerTime + tick() end

Then you could use it in a script like this.

local getTime = require(Game.ServerScriptService.Time)

print(getTime())
wait(1)
print(getTime())

This uses the utc time zone, because roblox servers are run in different zones I used time api. If you are just trying to get how long it has been that will be fine but you can't get a player's current timezone.

The os.date function is useful for this. It can return a date table for either UTC time or local time.

Example usage:

local date_table = os.date("!*t") -- this is for UTC time, "*t" would be for local time
print(date_table.month) --> 5
print(date_table.day) --> 26
