And it shows int he post bar on my screen as having been posted at 12:08 PM. My screen clock and OS clock are set at GMT-5, EST. This happened one time before some years back but I don't remember the fix or outcome.
Oh, well. I guess I'll just enjoy the time travel........
The actual displayed times are all set relative to the client-side clock so any misconfiguration there will distort the displayed times. You may also wish to try another PC or mobile device for a moment to see the result.
But please let us know your findings when you have identified the cause as I certainly would like to know if it turns out to be anything other than the above.
