Time measures the passing of events.

Different people relate to time differently.

Jesus came in the fullness of time.  Jesus fulfilled the prophecies of the waited-for Messiah.

Galatians 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,

5 To redeem them that were under the law, that we might receive the adoption of sons.

Yet the Pharisees did not recognize him.    They were still looking for someone to come in the future.  On God’s timetable, the fulness of time had come, the Messiah was in the now, yet the Pharisees still looked to the future.

One of the last things Jesus said, after he was resurrected from the dead, and before he ascended into heaven, was about time.

Acts 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?

7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.

This talks of the time of the end.

Daniel 12:1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.

2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.

3 And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever.

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.

5 Then I Daniel looked, and, behold, there stood other two, the one on this side of the bank of the river, and the other on that side of the bank of the river.

6 And one said to the man clothed in linen, which was upon the waters of the river, How long shall it be to the end of these wonders?

7 And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.

8 And I heard, but I understood not: then said I, O my Lord, what shall be the end of these things?

9 And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end.
