Jesus didn't say noone will know the time,
but that noone knew at that time:

Mark 13:32
Of that day and that hour knoweth no man...

1 Cor 2:11b
The things of God knoweth no man, but the
Spirit of God.

John 16:13
Howbeit when he, the Spirit of truth, is
come, he will guide you into all truth...
and he will shew you things to come.

Amos 3:7
Surely the Lord GOD will do nothing, but
he revealeth his secret unto his servants
the prophets.


While no man knows the day now, those
Christians who are alive at the abomination
of desolation will know the day:

Dan 12:11-12
From the time that the daily sacrifice shall
be taken away, and the abomination that maketh
desolate set up, there shall be a thousand two
hundred and ninety days. Blessed is he that
waiteth, and cometh to the thousand three
hundred and five and thirty days.
