Relativity is not a leap second issue, it's a calibration issue. You can't just move an atomic clock and keep counting. Even between slightly different elevations on earth, you get different raw numbers.
So unless you differ from Earth's calibration on purpose, you won't lose 56 microseconds a day. You'll stay in sync.
Let's say you do something reasonable, like put an atomic clock on the moon, or anywhere really, but let's stick with the moon.
You build your clock, you sync it with the Naval Observatory., and launch it to the moon.
48 years later, who shows up? That's right, the leap second.
Your lunar clock is losing 56 microseconds a day due to an insufficiently curvy spacetime (e.g. gravity).
