It must, given that such effects have been measured for about a half century:

Indeed.  One contributor to this forum is so irritated that he denies that the 
next leap second
will properly be designated:

                          2015 June 30,     23h 59m 60s
    https://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat

... because that contradicts the congruential scheme of time notation obsoleted 
by the
adoption of UTC in 1972.

I grant that:

o UTC with its leap seconds is a PITA to IT personnel.

  POSIX hadn't that foresight.
