@LoLoSowweyms, when we are at home postpandrial glycemia is 2 hrs after starting to eat. In restaurants I don't know if there is consensus. So better sin by excess, do it at 17 and 18.
It is usually two hours after finishing (18:00 in your example).But it depends on each person (with other diseases, such as gastroparesis) and / or your endocrine / doctor;You know, every master has its booklet.
