Hi,

Could you please tell me if the sentences I have written are possible grammatically or not?

-Six years have passed since she has left New York.

-It's a long time since they left New York.

-It's a long time since they have left New York.

-It can be a long time since they left New York.

-It can be a long time since they have left New York.

Thanks...

-It's been a long time since they left New York.

-It's been a long time since they [STRIKE]have[/STRIKE] left New York.

-It [STRIKE]can [/STRIKE](it doesn't make sense to me) be a long time since they left New York.

-It [STRIKE]can [/STRIKE](it doesn't make sense to me) be a long time since they [STRIKE]have[/STRIKE] left New York.

Thanks...
