I See Tomato Blossoms. How Long Until I See Fruit?

[Pashenfish]

So glad this forum exists!
I'm a newbie at tomato plants - I've got 3 black krims & 3 Purple cherokees that are just over a month old. All are doing great - just got my little yellow flower blossoms. So, question is - how long until I see fruit? I'm salivating over the thought of fresh brucshetta! I'm confident they're getting pollinated and soils good.
What's the normal life cycle? do the little yellow blossoms indicate fruit is on it's way?
thanks in advance
oh - any basil info around here?

I am a newbie too, but I know that those yellowish buds will start turning into little green fruits in a couple of weeks after first bloom. I transplanted my plants in mid April and I already have several marble sized fruits on one plant and a golf ball sized one on another.

Take care.
