I said that it should be eaten before noon. I'd say I consider 6 PM to be the start of the evening.
It was obviously said with humor, but hummus is commonly eaten earlier in the day in Israel. It is considered a "heavy", and as such more suitable to be eaten at lunchtime.
I'd add and say that the absolute most of hummus restaurants close before 5 PM.
In general, many (probably most) people in Israel have their dinner (as in main meal) at lunchtime, usually somewhere between noon and 3PM. Those who keep kosher, as well as most workplaces, make this a meat based meal. In the evening, supper consists of lighter fare, often based on dairy and eggs. This is not true for holidays and Shabbat dinner (at Friday evening) where dinner is served in the evening, and lunch is often lighter.
