time.nist.gov is where I go to update my computer time. I usually do it right before I set or check my watch to take a few sights. I have no idea how close it is to actual GMT. Can't be more than a few seconds off however. I assume there will be some error just in the transmission of a 'signal' over the internet, through servers etc.
I used to be a normal person, then I discovered how to locate myself on this planet using a star.
