For testing the existence of superposition of macroscopically distinct quantum states, Leggett and Garg [Leggett A J, Garg A 1985 Phys. Rev. Lett. 54 857], proposed an inequality based on the assumptions of `macroscopic realism', `noninvasive measurabilty' and `induction'. These assumptions in a slightly dierent form have been used to derive a temporal version of Bell's inequality [Brukner C, Taylor S, Cheung S, Vedral V (e-print quant-ph/0402127)]. This inequality is violated in Quantum Mechanics and thus establishes non-locality of quantum correlations in time. We compare various nonlocality arguments in this temporal scenario.
