This will not answer the question but provide some background. (The answer to this question is impossible without a grander scheme of eschatology and prophetic interpretation.)
The two words at question here are:
זִמְנִ֣ין (zimnin) = times
The root word זְמָן occurs only 11 times in the OT, all but one (Ezra 5:3) occur in Aramaic portion of Daniel, namely, Dan 2:16, 21, 3:7, 8, 4:36, 6:10, 7:12, 22, 25. Thus it means (by BDB)
time (probably loan-word from Old Persian zrvan, zarvâna, time, age, NöM 152 Scheft45; compare Biblical Hebrew (late); and (on change
of ν [b] to m) FräZA iii. 52; Nabataean זמן, Palmyrene (Nabataean) זבן
Lzb266; Lzb268 SAC48. 49); — absolute ׳ז Daniel 2:16; Daniel 7:12;
emphatic זִמְנָא Ezra 5:3 +; plural absolute Daniel 6:11 +, emphatic
זִמְנַיָּא Daniel 2:21; — time: specified time Daniel 2:16; appointed
time Daniel 7:12,22, compare Daniel 2:21; בֵּהּ זִמְנָא at that time
Ezra 5:3; Daniel 3:7,8; Daniel 4:33; (festival) seasons Daniel 7:25;
time, occurrence, Daniel 6:11; Daniel 6:14 three times in the day.
וְדָ֔ת (w'-dat) = and law
The word דָּת occurs 14 times: Ezra 7:12, 14, 21, 25, 26 (twice), Dan 2:9, 13, 15, 6:5, 8, 12, 15, 7:25. BDB gives these meanings:
1 decree of king Daniel 2:13,15; Ezra 7:26; with suffix Daniel 2:9
decree against you.
2 unchangeable law of Medes and Persians Daniel 6:9; Daniel 6:13;
Daniel 6:16.
3 law of God (in mouth of non-Jews): Daniel 6:6; Ezra 7:12,14,21,26,
so (absolute) Daniel 7:25; laws of God Ezra 7:25.
Note that BDB classifies (correctly as is obvious from the context) Dan 7:25 as the Law of God.
Therefore, whatever Dan 7:25 prophesies, it has something to do with changing times in [God's] laws.
