i If she beats him he’ll claim she cheated. [non-deictic past]
ii If you eat any more you’ll say you don’t want any tea.[non-deictic present]
The preterite and present tense inflections on cheat and do indicate that Tr is respectively anterior to and simultaneous with To, but here To is clearly not Td. The time of the (possible) cheating is not anterior to the time of my uttering [5i], but to the time of his (possibly) making a claim of cheating.
— The Cambridge Grammar of the English Language, p126
I can understand To (time of orientation = utterance time), yet don’t get what the ‘deictic time (Td)’ is. Would you let me know the Td?
