    The Javascript are sending your located time and time zone to website when you are browsing the web by mainstream browser, if your time setting wrong and stop the automatically updating time it will be a big fingerprint also you are using Tor, can I stop the Javascript sending time or random the time to confuse the website? at the same time when I using other browser there is another time?

    I recommend asking this on Tor StackExchange < http://tor.stackexchange.com/ >. Tor developers will see your question there. Or you could ask on the tor-talk mailing list.

    Yea Javascript is a pain when it comes to revealing your time on your pc because sites can tell what country you are in. I wish some one would create a filter addon for firefox which blocks javascript from revealing the time on your pc.

    The only ways around this is to disable javascript or change the time on your pc.

    Can NoScript filter out time requests?

    Not unless you block javascript completely no I don't think it can. you could always test on http://browserspy.dk/date.php

    I used to have my task bar clock different to my pc time. The time on my pc was fake and the time on my task bar desktop etc was real.
    That way sites couldn't see my real country of origin. But I now disable javascript on tor.

    I'm surprised that NoScript doesn't allow the user to filter these. Apparently my Proxomitron filterset does filter out these requests. Browserspy couldn't obtain my system time with javascript enabled.

    Just to note: When running Tor, Tor needs to be set locally on your computer to UTC if it is to resolve .onion websites as opposed to so-called 'clearnet' websites which is where we all normally websurf.

    UTC (Universal Time Coordinate) time is easy enough to set (as root/admin) before bringing up your network interface on your computer. Tails will automatically set the UTC time on your computer prior to a full GREEN status on the Panel GUI, and should never be used before a full GREEN status is attained.

    I recommend you not mix your normal use user profile on your computer with use of TOR. It is best to separate both your normal use user profile from any TOR user profile, and even better if you use another OS like Tails on a USB flash drive or CD/DVD, or from within a VM hooked up to a VPN website.

    Tails uses UTC (Greenwich time).

    Remember too that you'll want an accurate time cause HTTPS connections with sites won't work:

    Interested here too. Is the BIOS time independent from the taskbar time? If so, Im guessing thats the way.

    Now I have new think, The PC time send to the website needs sometime transport because the Tor connect to website is much slower than directly connect, the website can not get your real time, therefore the real time show on ip-check.info is only show to you not the website, the website only can see the your PC time after sometime later

    I have the similar problem that my time between Windows and Linux are different, I had to adjust my timezone to show me the right time and would leave a good fingerprint.

    I don't know if there is a date command on any Windows platforms for setting time, but in Linux there is a date command that can do just that.

    To set the local time on your normal Linux OS, issue the following command as root(admin) user:
    In the following command, I am setting the local time on my computer by setting the UTC time according to my 'atomic' watch (EDT: 4 hours behind UTC) on June 5, 2014, while (EST: 5 hours behind UTC) which occurs Nov-Mar :
    Code:
    # date -u 06051957
    
    Look for a man page on your Linux/Unix system for the date command, i.e.: # man date

    Code:
    C:\Users\Beardy>time /?
    Displays or sets the system time.
    
    TIME [/T | time]
    
    Type TIME with no parameters to display the current time setting and a prompt
    for a new one.  Press ENTER to keep the same time.
    
    If Command Extensions are enabled the TIME command supports
    the /T switch which tells the command to just output the
    current time, without prompting for a new time.
