While I see SF in Central European time. Which is my time zone. Which suggests that the clock for SF is using the computer's local time zone instead of the city's time zone, and that you are in the Eastern time zone.

Looking at the code - wow, that's a lot of copy&paste or autogenerated code instead of using a loop. The relevant code is in http://www.pravindaryani.com/officehours/js/main.js :

    //USA/LA Time
    var latime = document.getElementById('la_time');
    var time = moment().tz('America/Los_Angeles');
    latime.innerHTML = time.format('hh:mm A ');

    //USA/SF Time
    var sftime = document.getElementById('sf_time');
    var time = moment().tz('America/San_Francisco');
    sftime.innerHTML = time.format('hh:mm A ');

It's using time zone code from http://momentjs.com/static/js/global.js , and a quick check show that there is no entry for "America/San_Francisco". It looks like the code only applies the correct offset from localtime if the timezone exists, hence why we get different times.

FWIW, it's now fixed.
