Front Cover
Apress, Nov 22, 2006 - Computers - 153 pages

Have you ever tried to figure out why your computer clock is off, or why your emails somehow have the wrong timestamp? Most likely, it’s due to an incorrect network time synchronization, which can be reset using the Network Time Protocol. Until now, most network administrators have been too paranoid to work with this, afraid that they would make the problem even worse. However, Expert Network Time Protocol: An Experience in Time with NTP takes the mystery out of time, and shows the network administrator how to regain the upper hand.

This book is a fascinating look into NTP, and the stories behind the science. Written by Peter Rybaczyk, one of the foremost experts on NTP, this book will show the network administrator how to become more comfortable working with time.

Page 32 - When I have seen the hungry ocean gain Advantage on the kingdom of the shore, And the firm soil win of the watery main, Increasing store with loss, and loss with store; When I have seen such interchange of state, Or state itself confounded to decay ; Ruin hath taught me thus to ruminate, That Time will come and take my love away. This thought is as a death, which cannot choose But weep to have that which it fears to lose.
Page 32 - Time, thon shall not boast that I do change : Thy pyramids built up with newer might To me are nothing novel, nothing strange ; They are but dressings of a former sight.
