How much decision time is given for tenure-track offers

I've been applying for tenure track positions in computer science.

Recently I visited university X for an interview and they have hinted that they are likely to offer me a position after my second visit. Assuming all goes well, how much time can I expect to be given for deciding on that offer?

I have also applied to several other places where any decision won't be made within the next few months. So my worry is that I might receive an offer from X "too soon" and hence won't be able to also take into account other opportunities.
