Solved How do I stop this site from checking the time on my PC?

It's Falkon. It's the same on Firefox.
How do they read the time? Is Falkon's telemetry so advanced?

You could try disabling javascript in your browser settings. There are also extensions in firefox to block javascript on specific domains.

Thank you. I just don't want the site to read my PC's time in any way. I went to the site to check the time, not to sync with the site... How do they see my PC's clock? What channel do they use to read the information? How do I close that channel? JavaScript simply disables the site's functionality.

Your location (and ultimately the timezone) is identified from the machines IP address. Try www/tor-browser or a proxy server to circumvent your IP address.

Thank you. Oh, and one more thing: the Tor browser, like LibreWolf, also leaks time.
But there's some information out there:
$ doas whois time.is
Code: 
nserver:      A.NIC.IS 185.93.156.10 2001:67c:6c:56:0:0:0:10
nserver:      B.NIC.IS 185.93.156.154 2001:67c:6c:f056:0:0:0:154
nserver:      C.NIC.IS 2001:500:14:6116:ad:0:0:1 204.61.216.116
nserver:      D.NIC.IS 194.146.106.58 2001:67c:1010:14:0:0:0:53
nserver:      E.NIC.IS 194.0.25.41 2001:678:20:0:0:0:0:41

executing the "date" command on your machine gives "access" to your clock.
Maybe if you open the broswer debug console or something before going to the website you can see what the http/javascript is doing that triggers the problem?
 
Google AI,
Firefox (Highly Recommended):
  • Enable "Resist Fingerprinting" to force the browser to report UTC+0000 regardless of your system settings.
  • Action: Go to about:config, search for privacy.resistFingerprinting, and set it to true.

By using JS (javascript) in your browser. There's https://time.is/js/t2025-10-05.js which does getTime() and other get*() functions to get the system time.



You'd be royally "fragged" if your browser could execute date command. 😈

I don't disagree; is there something in the browser itself that has the ability to do "date"? Like how the WebRTC bits can have access to your hardware (camera/mic) (yes I realize the browser asks for permission) maybe something during application startup it reads date. Most browsers when you exit save some sort of session data/update profile (maybe timestamped) so perhaps exposed websites?

That's all conjecture on my part
 
HTTPS certificates are only valid between certain dates. HTTPS will not work if your browser does not report your date is within a certain window. I think the browser gets that from /etc/localtime
 
Someone has been kind enough to write a script instructing how to get date and time from a user's browser using Javascript. I think that giving the user control over their timezone on a website is the right move myself. I make sure and give users the option to set their timezone. This way they can set their timezone to appear however they prefer it. :D

Hope this link is helpful.

Getting a date in the current user's timezone with JavaScript

Last week, a friend of mine nerd-sniped me into an interesting challenge. An API they’re using returns the date as a string in a fixed timezone (in their case, Denver, Colorado, USA), like this… let dateFromAPI = '2025-01-31T11:50:15'; And they wanted to display it as a formatted string in the...

This is sort of related, SirDice Crivens @GodsOfFreeBSD @GodAlmighty. You will be terrified one day. You will suddenly lose internet connectivity. Everything will seem normal, the ethernet will be up and connected, but you will all of a sudden not have connectivity. You'll pull your hair out, and you'll still be connected but without connectivity.

Well, the reason will be that your computer clock will be set wrong. Your BIOS battery will have died, you'll have to type in your current time and date, and you will enter 2025 instead of 2026 by accident. Nothing will warn you of this, you will not notice the typo because you were sleepy, and you will lose your mind because suddenly your internet will not work.

And you will blame it on the universe, on FreeBSD, on hackers, on hardware, and you will lose a lot of time troubleshooting. But it's your date being off by 1 digit. And FreeBSD will do nothing to ward that off. And it might affect your life significantly because it might happen on your work morning when you must do something urgently, it might just happen at the worst time for that one person out of 100 who will experience it maybe. Maybe it will result in a life threatening situation because of the confluence of events.

Can someone please fix this? Maybe some sort of a warning that your clock is suddenly off by a lot? Just a warning, so that the end user will know? It's such an easy fix (and no, not by using a lower kern.securelevel).

I have that happen briefly daily with a router restart script :p (I gotta time it better with 2 routers; my laptop's on the one that takes longer)

Firefox taking long to start is my first clue (unable to resolve DNS with DoT); the 2nd is Firefox telling me the SSL on a page won't load because of the date :p

If that happens, it's because my CMOS reset which shouldn't happen. My computer boots normally at defaults so I likely wouldn't notice, but CMOS clock being off is a good indication I need to reboot and check stuff out.

Also wouldn't one of the ntpd options at install-time cover incorrect time/date at boot?


I'm not sure how other apps might notify about incorrect time/date for internet connectivity, but I feel WAN shouldn't be a requirement at a core, and like the idea of apps not knowing or caring about incorrect time/date directly (time/date is the OS's responsibility). It's a nice hint if it's reasonable though like Firefox.

If you are running at kern.securelevel above 0, ntpd is limited at changing clock to maximum one second at a time (for obvious security purposes), so it won't correct when CMOS clock so drastically off.

This can be corrected in userland, but this affects every user of FreeBSD, so why not create some sort of a fix?
