The stomach typically empties every 20-30 minutes. After that it's a matter of the individual's metabolism and disgestion rates.
Within an hour and a half you should start to expereince some discomfort, feverish, irritable bowels grumbling, then later diarrhea and vomiting.
It really depends on what you have contracted. Viruses can make you very sick very quickly (e.g. the norovirus that many folks got on the cruise ships). Staphylococcus aureus, Bacillus cereus and Clostridium botulinum form toxins and can get you sick in a matter of hours. Salmonella and E. coli O157 take 1-8 days. Some take weeks, even months to manifect themselves (e.g. Listeria monocytogenes).
