![]() Parts.mins = math.floor( diffSeconds / MIN ) - Get minutesĭiffSeconds = diffSeconds - parts.mins * MIN Parts.hours = math.floor( diffSeconds / HOUR ) - Get hoursĭiffSeconds = diffSeconds - parts.hours * HOUR Parts.days = math.floor( diffSeconds / DAY ) - Get daysĭiffSeconds = diffSeconds - parts.days * DAY If you’re expecting it to be over a year I’d probably do the division manually, which would look like this: local MIN = 60 year part of the response from os.date, though this method begins to produce inaccuracies if the year is a leap year. If your countdown will span years, you’d also need to account for the. Print( ( 'There are %i days, %i hours, %i minutes and %i seconds until 12:00 BST on 20 April 2020!' ):format( countdown.yday, countdown.hour, countdown.min, c ) ) here you would update a GUI or whatever it is you need to do Local countdown = os.date( '!*t', diffSeconds ) - The first argument is important to say we're working in UTC so no offsets get applied Local diffSeconds = TARGET_TIME - os.time() In your code you would then find the current timestamp (again, in UTC) and calculate the difference: local TARGET_TIME = 1587380400 - 12:00 on 20 April 2020 BST This is always in UTC/GMT in seconds since 1 January 1970, so this is technically 11:00 on the 20 April 2020 in UTC due to the timezone difference with daylight savings. The timestamp 1587380400 is provided as the Epoch timestamp. Using the website I linked to, I enter the time in my local format, and select Local time for the timezone: Let’s take the example of a countdown to 20 April 2020, at 12:00 (midday) BST (my local timezone right now). Sure! There is also the built-in function os.date which can be given a time argument to save you having to do the division by 60 and 24 yourself. Local minuteRemainder = hourRemainder % (60) Local minutes = math.floor(hourRemainder / (60)) Local hourRemainder = daysRemainder % (60*60) Local hours = math.floor(daysRemainder / (60*60)) Local daysRemainder = monthRemainder % (60*60*24) Local days = math.floor(monthRemainder / (60*60*24)) Local monthRemainder = (yearRemainder % (60*60*24*30)) Local secondsBetween = os.difftime(day, os.time()) - Good example for os.difftime and os.time() Local countdownText = countdownGui:WaitForChild("CountdownText") This means os.date() is great for making a live event or countdown.Ī simple countdown script for this could be something like this : local countdownGui = script.Parent Os.date() returns the date in the format of day, month, day of month, hour, minute and year. Good example is the tick() code and the os.date() code. This is essential tick() for every player at the same time. The o differences is that it runs on the current UTC time, meaning that this is better for Server-sided stuff and that it returns a slightly more floored number than tick(). Os.time() returns the number of seconds since the Unix EPOCH, just like tick(). Keep in mind that this runs on UTC time so it’s the same for every player. Do something you want to measure the performance of: Making this a very good substitute for the now somewhat deprecated tick() function.Īn example script for this could be this - Record the initial time: This value has high precision, about 1 microsecond, and is intended for use in benchmarking. ![]() ![]() Os.clock() returns the amount of CPU time used by Lua in seconds. Os is a library filled with 4 different functions. Print("5 or more seconds since game start") A script for that could be : game:GetService("RunService").Heartbeat:Connect(function() This can be good for a message or announcement system or something along those lines. Time() returns the number time in seconds since that game Instance has started running. ![]() Keep in mind that this runs on the players device’s time not the global time. Game:GetService("RunService").Heartbeat:Connect(function() If you can get it working right tick() is great for accurate waiting.Ī script to see this could be like : local StartTime = tick() Read this for more on tick() getting deprecated : Luau Recap: June 2020 - #6 by zeuxcg 1649938990.301689 - Number of seconds since January 1st, 1970(when I made the post).Ī good way to use tick() is for coders to control stuff with the time. It’s still very good but there is other options in the os library. tick() has now gotten somewhat deprecated by Roblox. Tick() returns the number of seconds since January 1st, 1970 according to the devices time. In this tutorial I’m going to be teaching you guys os, time and tick and what they are and how to use them. ![]()
