I knew time dilation had been proved experimentally, but I never knew that GPS had to allow practically for the effect. Very interesting... thanks.

So you don't have to reach relativistic speeds, and it's not just a hypothesis. Carl From: Michael B. Smith [mailto:[email protected]] Sent: Tuesday, June 30, 2009 9:51 PM To: NT System Admin Issues Subject: RE: GPO's and remote servers boys boys boys... relativistic time is still only a hypothesis. while it apparently describes certain events that occur in the universe, until a human object is accelerated to relativistic speeds, decelerates, and then returns to earth (with or without an additional relativistic interval during the return), and has the results of the internal clock evaluated - it cannot even be considered a theory - much less a fact. also, even IF it should be a theory - who knows what are the special corner cases to which it applies and to which it may not? einstein himself predicted and described continua in which relativity may/would not apply. any object which has mass curves space-time. while einstein depended upon that, it wasn't part of his special-relativity theories, but was instead an axiom of the lorentz-fitzgerald equations (which described and explained the failure of the michelson-morley experiment) and independently derived by einstein as a part of general relativity (years later). ________________________________ From: Steven M.

Webster From: Carl Houseman [mailto:[email protected]] Subject: RE: GPO's and remote servers Computers don't care about time zones, they exist only to display time for humans. Any time settings you establish are converted to universal time based on the TZ of your machine.
