Probably not -- time isn't that relevant before society puts you on the path towards hourly labor. I learned in elementary, but then I also grew up with digital clocks like most folks under 50.

Edit: apparently we have either a lot of on-the-clock preschoolers or folks who don't know when digital clock radios were invented. Perhaps both. If you cared about the clock time before you were 5 I feel sorry for you.
