"Tea time"

I heard from my wife that when someone says "tea time"in Japan they are referring to a time around 3 o'clock (in the afternoon). But,in the UK this time refers to around 5 or 6 o'clock. In the UK "tea time"usually means the last meal of the day (although sometimes some people have "supper" much later). I must add that my family do NOT "over-indulge"by having that fourth meal! Haha..
