is not here vs. not be here

[juelka]

Hello, I would like to know if there is any difference, when it comes to the meaning, between:

It's important she is not here at 6.
and
It's important she not be here at 6.

As far as I'm concerned, both options are grammatically correct.

I'm not sure what either of them means.

There is no difference in meaning and both are used. The second is an example of the subjunctive mood. It has several times been claimed in this forum that the subjuncctive is now rarely used in BrE, but I know for certain that it is often used in AmE.

It's important she is not here at 6.
and
It's important she not be here at 6.

@probus They may very well be subjunctive mood, but I still don't know what they mean. Is somebody saying somebody shouldn't show up somewhere at a certain time?

Imagine for example that you're planning a surprise party for your friend and you don't want her to be there in case she finds out what you're doing.

Hello.

I would like to know if there is any difference, when it comes to the meaning, between:

1. It's important she is not here at 6 six.
and
2. It's important she not be here at 6 six.

As far as I'm concerned, both options are grammatically correct.

Note my changes above. "Hello" is a standalone sentence here so should be followed by a full stop. Only follow it with a comma if the next word is someone's name or something like "everyone" or "mate". Write the numbers zero to twenty (inclusive) in words, not digits. Whenever you give us more than one sentence to look at, number them. It makes it easier for us to refer to them in our responses.

I wouldn't phrase it that way. That's for sure! I wouldn't expect anybody to know what I was saying.
