Time is a really tricky and interesting topic. I would start with:
"From Sundials to Atomic Clocks: Understanding Time and Frequency"
http://www.nist.gov/timefreq/general/pdf/1796.pdf
"Originally published in 1977, this full-length book provides a comprehensive, easy-to-understand introduction to the field of time and frequency. Readers of nearly all ages and educational backgrounds should find it enjoyable. 306 pages."
