Unix format in Google Chart GUI format?

It’s hard for me to figure out the date and time format using Google Chart. I used example [1], where the date and time format is set to a simple month and year, but I changed it to introduce input of type datetime. An example is available on the following page:

http://www.sccs.swarthmore.edu/users/09/leo/cgi-bin/viewer.php

The beginning of the code is as follows:

data.addColumn('datetime', 'Date');
data.addColumn('number', 'Active or not');      
data.addRows(1768);
data.setValue(0, 0, new Date(1306192258));
data.setValue(0, 1, 1);

Why will Google change the date format to January 15, 1970? (The time of the beginning of the era?)

Thank!

Try the following:

data.addColumn('datetime', 'Date');
data.addColumn('number', 'Active or not');      
data.addRows(1768);
var d = new Date();
d.setTime(1306192258*1000);
data.setValue(0, 0, d);
data.setValue(0, 1, 1);
