    hi,
    I want to know current system time in client side(the Unity) to sync with server side. I checked the Time class but seems there's no such variable in it.
    Does anyone know about this?
    thanks in advance.

    Use the .Net Library to get the system time :)

    You'll need to use the Mono System.DateTime class. To get the current time, you simply query
    Code (csharp):
    1. System.DateTime.Now
    If you'll be using it often, you'll need to import it
    Code (csharp):
    1. import System
    and then you can just refer to it as "DateTime" and "DateTime.Now" when you use the class.

    The docs for DateTime can be found here. Do make a note of the note on the page, it does not use Unix time. If you need to compare against that, you'll probably want to convert it to UTC time, and use System.DateTime.UTCNow and compare those.

    Here is a short example on how you would get the UTC value.

    System.DateTime.UtcNow.ToString()

    And here is if you want to get a String back formatted in some specific way

    System.DateTime.UtcNow.ToString("HH:mm dd MMMM, yyyy") // returns "12:48 15 April, 2013"

    Is there a way of registering time when you exit a Unity application (i.e. you press play and stop the app) or perhaps when you exit a standalone build?

    Using the following simple line of code, I can write to the console when my start button was pressed, so I wonder if I could do the same when the app is quit, so that the difference would be the length of the session?

    Code (CSharp):
    1. Debug.Log("Start Button pressed @ " + DateTime.Now);

    Eh what is you specific use case? Getting the current time in-game while the game is not running is obviously not possible.

    You can't do anything when the game's off. That's kind of the point of the game being off!

    The easiest thing is to store the time when you turn the game of (PlayerPrefs is adequate for this), and then check it when you turn it back on again.

    Of course, it'd be really easy to cheat, as the playerprefs are stored on the users device and is changeable. If you want to avoid that, you'll have to have an online server where you store the current state of the user's game. If it's for educational purposes, don't worry about that.

    Could you use the .NET to get the current time, set a "world starting time" to say 01 jan 1990(or when you first start the game), and work how how much time has passed since then?

    adding on "candy" or w/e incrementally each day?

    (ofc this would be abuse-able with changing the system clock, much like fallout shelter, etc)

    How I can change the date language into another language? It's default is in English. How can I change it to French? For that example "15 Avril 2013" instead of 15 April 2013?

    You'll want to specify the fr-FR culture in the ToString method. The documentation with examples are here.

    Hi and welcome. As you can see right at the bottom (which is kinda stupid layout imho), DateTime has a property for Day. Or Month. Or Year. Or basically anything else you can get from it, so you can easily access any particular part of the time saved in it: https://docs.microsoft.com/en-us/dotnet/api/system.datetime?view=netframework-4.8

    Generally speaking, it's always worth to just have a quick look at the interface of such structs to see what they do. So a quick google search can, in most cases, give you the result a lot faster compared to asking on the forum. Of course, if you didnt find anything, asking is always fine.

    Relevant Answer using Unity 2019.2.13:

    Added this function to one of my c# MonoBehavior Unity scripts and reference it elsewhere when I want the build time to be displayed on an info screen. OnValidate runs when there's any change in unity or when build is run. Doesn't need anything else, OnValidate only runs in the editor environment while NOT in play mode. Works perfectly for me and is super simple. It's even visible in the inspector so you can see the format. Use string formatting if you want to clean it up.


    Code (CSharp):
    1.     public string autoGeneratedBuildTime;
    2.  
    3.     private void OnValidate()
    4.     {
    5.         autoGeneratedBuildTime = DateTime.Now.ToString();
    6.     }
