aply ocean modifier
at frame zero got to time property field of ocean modifier press i
go to frame 100 or so change time, press i again

nothing happens the ocean stays static

When you have the animation playing, hover your mouse over the “time” setting in the modifier panel briefly…
Also make sure you have the time difference set to be significant. i noticed that when i went from 0.0 to 1.0 over 250 frames it barely moved, changed it to 0.0 to 25.0 and worked fine.
