To make it a little simpler; does God lie?
Dan 12:4 But thou, O Daniel, shut up the words, and seal the book, [even] to the time of the end: many shall run to and fro, and knowledge shall be increased.
And did Daniel succeed in sealing up the book?
Dan 12:9 And he said, Go thy way, Daniel: for the words [are] closed up and sealed till the time of the end.
God Himself guarantees to us that the book of Daniel was indeed sealed up until the "time of the end".
John Darby is long dead as well as his generation. So since his wasn't the last generation it was clearly not the "time of the end" and his doctrine, it would seem, is necessarily in error unless God allowed John Darby a personal peek past the seal, to create his private interpretation. 2Pe 1:20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
The beauty and majesty of God's design is truly found here in the seal on this book that defied opening for 2500 years. What we, in this last generation now find, is that it wasn't until AFTER the dates of 1948 and 1967 had passed that we were able to check the prophetic math problems that Daniel and John gave us 2500 and 2000 years ago respectively, which predicted dates as recently as 1948 and 1967 TO THE YEAR. This is an amazing study and one that will truly bless you, in every moment of your life. Your newfound understanding of world events and governments will stun you even just watching the evening news. And the mathematics prove it.
