Well, it did. My nine-year-old daughter has a hard time with me telling her it's
"a quarter to nine" when it is, in fact, 8:42. The convenience of rounding is
something I'm working to help her appreciate. There's a practical side, too: when
I'm trying to get her ready for school in the morning, she'll cling to the useless
fact that she has "three more minutes" before it's time to go, during which
she can supposedly write a sonnet, create a work of art, and find her socks, shoes and a
suitable coat. 'Perception of time', indeed.... -- Ian

somehow concerned that it might 'change our perception of time'.
