Latin C2: Consecutio temporum: sequence of tenses · Grammar

Every subjunctive in a subordinate clause takes its tense from the main verb. Primary sequence (main verb present or future): present subjunctive for the same time or later, perfect for earlier: Nescio quid agas, quid egeris. Historic sequence (main verb in a past tense): imperfect for the same time, pluperfect for earlier: Nesciebam quid ageres, quid egisses. Later actions use the future participle with sim or essem: quid acturus sis.
