Note that the precision of all this isn't so high as to make this

worse than 100 ms.
Any ideas?
I can tell you from experience that 100 ms will be visually
noticeable. More than you might think.
In any case, to get the display to update ON the second you'd have to
change the labels and such BEFORE the second actually occurs.
And you'd have to account for any discrepancy between the software's
clock and the unidentified "accurate clock". If the software doesn't
know what the accurate clock is, how would it know its accuracy, so
how could you know that a person won't see a difference, even if the
display is exactly "on the second"?
