Why Can’t My Clocks Keep Time Accurately?

A short article, directed mostly at the problem of synchronization, as applied to everyday life: your electronic devices display different times. Why? Because you always have to synchronize your clocks, no matter how good they are. The question remains, how often do you need to do this?

From the article:
