Even moving floors is enough to cause headaches these days!

"At F1's level of precision, even general relativity introduces problems; when technicians recently moved F1 from the third floor to the second, they had to re-tune the system to compensate for the 11-and-a-half foot drop in altitude."

I believe these guys measure Time and Time Distortion to compensate and be aware of exactly how much time dilation is taking place.

We are in a (small) gravity well, after all.

I'm sure time drift on satellites from Einsteinian time dilation is a pain.

What timezone do you set on servers in the cloud, considering they could migrate themselves to any physical location? Fun times in the future when inter-planetary vMotion is commonplace. :P
