What time system should I use?

[GalaxySMediaXz (Painful_Galaxy)]

Hello!

I’m here to ask what time system I should use. I used to use tick(), which worked perfectly, but since it’s been deprecated, I’m now using os.time(). Unfortunately, I’m not very happy with it. Its resolution is only to the second, which causes mismatched timing in the UI and other elements.

Is there a time system with the same resolution as tick() that I could use instead?

Thanks!

The Ultimate os, time, and tick Tutorial!

In this tutorial I’m going to be teaching you guys os, time and tick and what they are and how to use them. tick() tick() returns the number of seconds since January 1st, 1970 according to the devices time. tick() has now gotten somewhat deprecated by Roblox. It’s still very good but there is other options in the os library. 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…

os.clock() is your best option, as it calculates time to as near precision as tick(). The only difference is that it returns the amount of CPU time Lua uses, unlike the amount of time since Jan 1, 1970.

Also, tick() is not fully yet deprecated, but Roblox is slowly starting to not support it anymore, so it is recommended you switch.

Hope this helps!

You probaby replaced tick() with os.time() because they look like the same by their descriptions.

@sjr04

tick() gets the amount of seconds (+ milliseconds) from 1/1/1970 but in local time.

os.time() only gets the seconds (not milliseconds) from the same date but in UTC time.

But I think you should replace tick() with os.clock() instead if you want something similar.

@Tomroblox54321

os.clock() returns the amount of CPU time used by Lua in seconds. This value has high precision, about 1 microsecond, and is intended for use in benchmarking. Making this a very good substitute for the now somewhat deprecated tick() function.

“This value has high precision, about 1 microsecond, making this a very good substitute for the now somewhat deprecated tick() function.”

use DateTime.now().UnixTimestampMillis / 1000
it is better option than tick

For what though? You have no specified use case.
