The two ways to set the time are slew and step. When you step the clock you just set it to the correct time in one action. That is, the clock might say 10:21:13 one second and 10:15:10 the next. This means that the clock could go forwards skipping over time or even backwards the same way. When a clock is corrected by slewing on the other hand, it is adjusted by making the clock run slow or fast. This means that there is no jump, no going backward, but it can take a considerable length of time for the correction to be finished. Until the slew is finished, the clock is known to be incorrect. Since it can take a long time, slewing is generally used only if the time to be corrected is on the order of milliseconds. In some cases it can be used up to a correction of a couple of seconds, but rarely more than that. -- blu It's bad civic hygiene to build technologies that could someday be used to facilitate a police state. - Bruce Schneier -----------------------------------------------------------------------| Brian Utterback - Solaris RPE, Oracle Corporation.
