There is an interesting similar question though - does a world with
higher gravity have 'time' run slower - I believe the idea that 'rate of
change of time' is affected by gravity is suggested by relativity,
although don't ask me to explain it because its literally decades since
I did any serious physics :).

If you want a somewhat less serious reference, go find (I think) book 3
of the classic 2000AD series 'The Ballad of Halo Jones'. Quite an
interesting story based around the idea of a war on a planet where high
gravity slows everything down tremendously, and the logistic and
psychological problems that would cause.
