As every event in the universe can be reduced to interaction between particles via the 4 fundamental forces, can the same be applied to time? Could the flow of time be reduced to a particle that causes an instant of time, or is time an emergent phenomenon of the fabric or the nature of space? Or could time be an emergent phenomenon as a result of virtual particles?

Does this answer your question? What is time, does it flow, and if so what defines its direction? – John Rennie Sep 16 '20 at 14:52

The simple answer is that time is a dimension analogous to the three dimensions of space, and does not need a particle to "carry" it any more than "North" needs a particle to carry it.
