My watch was in sync with the page.  The watch was calibrated again when I came back in from outside, after about 20 minutes, time remained the same.
    I would strongly advise against using webbased time services for time 
    calibration. Even if the time server itself is correct, internal processes in 
    your PC and your ISP's network introduce time lags.
    Time signals obtained over the internet *never* can be accurate.
