Hmm,  gravitational time dilation it might complicate things ...  I
suppose it depends on whether your Mars clock is on the surface of Mars,
Earth or somewhere else.

Without an ocean or significant atmosphere I bet the rotation rate would
be more predictable than Earth - once good measurements were made.  The
dearth of observatories on Mars suggests the current error bars on
current rate estimates pretty wide.

Fun to think about that's for sure.
