Both. If you are racking up lots of miles, you go on miles.

If it sits a lot but gets a long trip and properly warmed up every
few weeks, go on time, within reason. 12 to 18 months.

If it rarely gets used and all the uses are very short trips where
it barely warms up and keeps the battery charged (two miles to the
train station, to the supermarket, to Church...) then you stay with
time for the oil changes and drop the intervals to six months.
