Well, isn't that a happy little question! If it's twenty minutes to seven, then it's almost time for the clock to strike seven o'clock. So, it's about 6:40, and you have a few more minutes to enjoy before the hour changes. Just enough time to appreciate the beauty around you and maybe even paint a little landscape scene.

False.
When someone says it's "twenty of", he/she means it is twenty minutes before an implied hour. For example, twenty of six is 5:40, twenty of seven is 6:40, twenty of eight is 7:40, etc.
It would help to know what the question was!
