I think that if we asked plants how they experience time, it wouldn't be this linear sequence of events, but the cycles of expansion and consolidation, as the absorbed energy and emerging structure feedback thermodynamically.

E.O. Wilson described the insect brain as a thermostat, though I came across an experiment showing that ants count footsteps as a navigation tool.

I think our left, logical brain functions as the clock and ruler, essentially sensing the structure expressed by frequencies, while the right, emotional side is the thermostat and barometer, sensing the energies in the amplitudes.

So we have to take into account how our physiological existence is the lens through which we sense reality.
