I was thinking about the MMN just now after reading this thread.  I have an
interesting, if non-canonical, explanation for both the MMN and Malkavian 
Time.

According to various sources, Malkav at one time was the wisest of the Antes 
and spent a lot of time searching for truths.  One day he found one that was 
so profound it caused him to lose his sanity, and this madness is passed down 
to his childer.  Okay, suppose what Malkav found was absolute knowledge of the
future.  No oracular hocus pocus or hazy predications.  Somehow he came to 
know specific events and dates.  He would have also known that this knowledge 
would doom him utterly.  So, he did what needed to be done.  Through some 
ritual, he inscribed the things that needed to be done and the dates when they
would occur within his very blood.  This knowledge would be passed down to 
each of his childer and would be revealed when necessary.  To hide this 
dangerous knowledge, he laid down madness on top of it.  So, each Malkavian is
irredeemably insane to hide the knowledge her blood contains.
