Any effort to localise an event in the vicinity of the Planck length scale, only where the quantum
gravitational effects are predicted to be observed, will invariably result in gravitational collapse. One must postulate noncommutative (NC) algebra between space-time coordinates, which are
now elevated to the status of operators, in order to prevent such a situation from occurring.
On the other hand, a consistent formulation of Quantum mechanics itself, with time being an
operator is a challenging and longstanding problem. Here we have given a systematic way to
formulate non-relativistic quantum mechanics on 1+1 dimensional NC space-time (Moyal
type noncommutativity) in a user-friendly way, which mandates the formulation of an equivalent
commutative theory. Although the effect of noncommutativity of space-time should presumably
become significant at a very high energy scale, it is intriguing to speculate that there should be
some relics of the effects of quantum space-time even in a low-energy regime. With this motivation
in mind, we undertake the study of a time-dependent system, namely a forced harmonic oscillator
in NC space-time and have shown the emergence of a geometric phase, which vanishes if the
NC parameter is put to zero, proving the fact that, the occurrence of geometric phase is totally dependent on the non-commutativity of space-time.
