俱舍論疏 21.107

21.107

論「四時遠性至亦名為遠」，如過、未世雖復俱依一法上立，相非是遠，處亦無隔，時分隔故亦名為遠。

In the treatise, "Fourth, distance of time […] is also called distant": for instance, the past and future worlds, although both established upon a single dharma, their characteristics are not distant and their locations are not separated, yet because they are separated by temporal divisions, they are also called distant.
