Firefox 27 does not have the option of enabling or disabling JavaScript.  Installing the addon of "SettingSanity" solves this problem. This thing adds back the removed options for JavaScript, Advanced JavaScripot Settings, loading images, and showing the Tab bar.

Maury, I tried outputting the exact same code you have on screen, and only the last line comes out when I run it after 6 pm on the system clock.

I did a manual line by line debugging of the script and figured I had to delete the hour = hour - 12 line for the script to run proper.

Any idea why this happened? Please help. Tnx
