This was "proved" in 1915, and many many times since then. The article just talks about how relativity describes how gravity affects the progression of time

crappy headline from science daily. The actual news here is the precision they calculated the time difference to.

It's a real shame how scientific news is regularly butchered by sensational and basically wrong journalism.
Half a millisecond per day? No way it's true. Half a microsecond, that's more like it.
We measured it this time...
We knew what the measurements would show, but still, no one had done it yet.
Not groundbreaking, not surprising, but science is ratchet is this was an incremental step that once done can be built on.
Eventually we're gonna have to prove all this shit anyways.
Edit:
The fact that it's not stable is pretty cool too. Very small variety, but still, on a very very small scale that may matter.
The authors of the original article cited by this news outlet did not measure any time on Mars in any way. They did a theoretical calculation of the time difference with Earth based on astronomical data about Mars like mass, orbit, etc.
Time runs faster on Mars and scientists just ~~proved it~~ provided evidence
Rampant, shitty epistemology is a huge sign that popular "science" is busted.
Imagine the wall peaking you could pull off on Mars, Counter Strike 7 is gonna be lit.
That will totally negate the slight ping disadvantage!
Bungie will still be like, “peer to peer servers are fiiiine”
I don't like this future where Bungie owns Valve
And on Mars, time runs faster on Earth.
Temporality. Little "t".
