Kisah Para Rasul 1:7

1:7 He told them, “You are not permitted to know ¹  the times or periods that the Father has set by his own authority.

Kisah Para Rasul 22:9

22:9 Those who were with me saw the light, but did not understand ²  the voice of the one who was speaking to me.

[1:7]  ¹ tn Grk “It is not for you to know.”

[22:9]  ² tn Grk “did not hear” (but see Acts 9:7). BDAG 38 s.v. ἀκούω 7 has “W. acc. τὸν νόμον understand the law Gal 4:21; perh. Ac 22:9; 26:14…belong here.” If the word has this sense here, then a metonymy is present, since the lack of effect is put for a failure to appreciate what was heard.
