<h2>Date and Time APIs</h2>
|
|
<p>The Date and Time APIs provide support for working with date and time values.
|
|
Using these APIs, you can do the following:</p>
|
|
|
|
<ul>
|
|
<li>Access the current date and time</li>
|
|
<li>Adjust the current time of your system</li>
|
|
<li>Determine if a time adjustment is currently in progress</li>
|
|
<li>Convert date and time values from one format to another format</li>
|
|
<li>Retrieve information related to time zone descriptions</li>
|
|
</ul>
|
|
<p>The date and time APIs include:</p>
|
