<li class="ulchildlink"><strong><a href="rzatiutc.htm">Coordinated universal time</a></strong><br />
|
||
|
|
Coordinated universal time (UTC) is a time scale that is kept by time laboratories around the world and is determined by using highly precise atomic clocks. The UTC time is accurate to approximately a nanosecond (billionth of a second) per day. UTC is located at 0 degrees latitude, the Prime Meridian.</li>

|
<li class="ulchildlink"><strong><a href="rzatitimemainapp.htm">Time maintenance application</a></strong><br />
|
||
|
|
Use this information to learn how a typical time maintenance application works. You can also view an example environment that uses Simple Network Time Protocol (SNTP) as a time maintenance application.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzatitimeadj.htm">Time adjustment</a></strong><br />
|
||
|
|
Learn how a time maintenance application automatically adjusts system time and how you can manually make time adjustments to the system time. Also, learn how a time adjustment is different from manually setting the time of day system value and why a time adjustment is the preferred method when changing the system time.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzatitimezone.htm">Time zone</a></strong><br />
|
||
|
|
Use this information to understand the time zones that are included with the system and their properties. You can use one of the time zones included with the system or create your own.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzatidst.htm">Daylight saving time</a></strong><br />
|
||
|
|
Use this information to understand daylight saving time (DST). Find out what DST is and which time zones use DST.</li>
