Considering that the existing experimental limit for [ital CPT] violation is still poor, we explore various possible ways to test [ital CPT] symmetry in [ital CP]-violating [ital B] decays at [ital e][sup +][ital e][sup [minus]] [ital B] factories. We find that it is difficult to distinguish between the effect of direct [ital CP] violation and that of [ital CPT] violation in the time-integrated measurements of neutral [ital B] decays to [ital CP] eigenstates such as [psi][ital K][sub [ital S]] and [pi][sup +][pi][sup [minus]]. Instead, a cleaner signal of small [ital CPT] violation may appear in the time-integrated [ital CP] asymmetries for a few non-[ital CP]-eigenstate channels, e.g., [ital B][sub [ital d]][sup 0] /[ital [bar B]][sub [ital d]][sup 0] [r arrow] [ital D][sup [plus minus]][pi][sup [minus plus]] and [ital D][sup ([minus])][sup (*)0][ital K][sub [ital S]]. The time-dependent measurements of [ital CP] asymmetries are available, in principle, to limit the size of [ital CPT]-violating effects in neutral [ital B]-meson decays.
