俱舍論疏 20.31

20.31

論「尊者覺天至立名有異」，此述第四計也。彼師意說：待過、現故名為未來，待現、未故名為過去，待過、未故名為現在。

On the Śāstra's statement: "Venerable Buddhadeva […] the designation established is different": this presents the fourth position. That master's intention is to say: in relation to the past and present it is named the future; in relation to the present and future it is named the past; in relation to the past and future it is named the present.
