Not sure what the grammatical name for this is, but the correct answer is the simple past tense of the verb:


It's time you went to bed. 
It's time you got a haircut.


This might be considered a slightly pedantic construct. Most native speakers of English would probably be more inclined to say:


It's time for you to go to bed.
It's time for you to get a haircut.


"All right, Johhny, it's time you ..........to bed."
Officially, I am studying computer science. However, what I am actually doing is computational neuroscience. More over, the research I do is mostly medical research.

I have noticed that there are programs for MD-PhDs. However, in most countries, there seems to be always some legal requirements one has to fulfill to enter such programs. These requirements are not given very clearly out in most cases.

With an M.Sc in computer science, can I apply to such programs? More trickier question is would it be wise..? I mean, I could just go to a neuroscience program. However, I would be also really interested to help people with psychological, neurological, etc. issues (work in hospital), when having the MD title is a must?
