What is the default time on a new clock?
Typically the time will be set to 10:10 on a clock. This is because it's the most appealing look on a clock from a retailer standpoint. It looks like a smiley face, shows the clock logo usually located under the 12 and gives a better presentation.
Most clocks and watches that are not already running will be displayed and sold with this time setting.

Hours in a week = 168
4 weeks per month = 168 * 4 = 672
9 months = 672 * 9 = 6048
There are 6048 hours in 9 months (on average)
Why do the years just seem to fly by so fast?
Time is but perception. If one perceives time as going fast than it "appears" to do so. When one is bored or waiting for something, time seems to slow as your perception slows as well.
