如何在 Selenium Chromedriver 中设置时区？

Question

I can't figure out how to set a timezone when using Chromedriver. Is there some ChromeOptions argument or something?

The issue is that when I go to some sites (for example, https://whoer.net ), it shows the system time that is equal to the time set on Windows. And I want to be able to change the Chromedriver's timezone somehow to perform timezone dependent testing.

I tried to set some chrome options:

Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("args", Arrays.asList("--disable-system-timezone-automatic-detection", "--local-timezone"));
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

It doesn't work.

Tried to do some weird thing using Javascript:

((JavascriptExecutor) driver).executeScript("Date.prototype.getTime = function() { return 1 };");
   

It didn't help either.

EDIT:

Found this https://sqa.stackexchange.com/questions/8838/faking-system-time-date-with-selenium-webdriver

Tried to execute javascript on page with the code copied from TimeShift.js like this:

((JavascriptExecutor) driver).executeScript("/*code from TimeShift.js here*/ TimeShift.setTimezoneOffset(-60);");

System time at https://whoer.net didn't change. What am I doing wrong?

Answer 1

As far as I know you can only do this with TZ variable or with Decker Selenium.

Were you able to find a viable solution to this however? I am trying to do the same exact thing and have found very little in the way of solutions. I'm trying to do it with Python. The Tz variable solution is limited to Firefox in windows and decker selenium is a nightmare to install on windows.

UPDATED PYTHON SOLUTION VIABLE (below)

os.environ["DEBUSSY"] = "1"

SEE: How to set environment variables in Python

I am not sure if there is a Java equivalent but this Python equivalent worked for me in windows but only in Firefox. If you find a Java equivalent then that's awesome but if this issue is important to you Python is the way to go! :). I believe you are limited to three letters in windows but full customisation in Linux operating systems. Eg UTC, GMT etc, etc,. Hope this was helpful to you. I spent ages looking for this but turns out I was overthinking it. Good luck!!

Answer 2

with new selenium 4, it can be done natively with CDP

    WebDriverManager.chromedriver().setup();
    WebDriver driver = new ChromeDriver();
    DevTools devTools = ((ChromeDriver) driver).getDevTools();
    devTools.createSession();
    devTools.send(Emulation.setTimezoneOverride("Antarctica/Casey"));

download the following maven dependency:

      <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>4.0.0-alpha-6</version>
    </dependency>

list of time zones can be found here

Answer 3

You can do it by using Chrome DevTools Protocol, and here is the python code:

driver = webdriver.Chrome()
tz_params = {'timezoneId': 'America/New_York'}
driver.execute_cdp_cmd('Emulation.setTimezoneOverride', tz_params)
