gh-126256: Update time.rst to use the same clock as instead of the same clock than (GH-126257)

Update time.rst to use `the same clock as` instead of `the same clock than`

The time documentation uses the same clock than time.monotonic instead of the same clock as time.monotonic, which is grammatically false. This PR fixes changes two instances of `the same clock than` to `the same clock as`.
(cherry picked from commit d0abd0b826cfa574d1515c6f8459c9901939388f)
