Clock incorrect, and adjusting in Date & Time doesn't help

Question

I have corrected this in date and time by updating the timezone and even manually setting the clock, but the time displayed by my computer is still based on the GMT timezone for some reason.  Thank you for your help. 

Answer 1

I'm using Snow Leopard, but I'm assuming it's in the same location. Enter /private/etc in Go>Go to Folder in the Finder menu, then scroll down to localtime.
localtime on mine appears to be an alias to /usr/share/zoneinfo. If I right-click Show Original on the alias localtime, I see that mine is set to New York in the zone America. Your localtime apears to be locked and doesn't allow you to make this change.
So try this, which should unlock localtime. Copy/paste the following command into Terminal in Utilities, then hit return. You will be asked for your admin password, which you won't see anywhere when you type it in, and hit return again.
sudo chflags nouchg /private/etc/localtime
Now try setting the time preference.
If this doesn't do it, one or two more steps may be required.
