<h1 class="topictitle1">Date formats</h1>
|

|
|
<div><p>There is no worldwide standard for the presentation of dates. Therefore,
|
||
|
|
the date format should always be stored externally as part of the textual
|
||
|
|
data.</p>
|
||
|
|
<p>The valid date formats on the operating system are:</p>
|
||
|
|
<ul><li>*MDY (Month, day, year)</li>
|
||
|
|
<li>*DMY (Day, month, year)</li>
|
||
|
|
<li>*YMD (Year, Month, Day)</li>
|
||
|
|
<li>*JUL (yy/ddd)</li>
|
||
|
|
<li>*ISO (YYYY-MM-DD)</li>
|
||
|
|
<li>*USA (MM/DD/YYYY)</li>
|
||
|
|
<li>*EUR (DD.MM.YYYY)</li>
|
||
|
|
<li>*JIS (YYYY-MM-DD)</li>
|
||
|
|
</ul>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Some operating system functions do not support
|
||
|
|
all of the previous date formats.</div>
|
||
|
|
<p>In database files, dates can be stored as:</p>
|
||
|
|
<ul><li>Normal numeric data fields</li>
|
||
|
|
<li>SAA<sup>®</sup> date
|
||
|
|
data-types</li>
|
||
|
|
</ul>
|
||
|
|
<p>When you store dates as numeric data, your application needs to specify
|
||
|
|
the format in which it is stored and presented.</p>
|
||
|
|
<p>When you store dates as data type DATE (L), you can specify the format
|
||
|
|
with the DDS keyword DATFMT on the database file. The date is shown in this
|
||
|
|
predefined format as character data, including the date separators.</p>
|
||
|
|
<p>If date sorting and other processing is needed, the date should be stored
|
||
|
|
in *ISO format (YYYY-MM-DD) and converted to another format during the input
|
||
|
|
and output operations. Write a high-level language routine to convert dates.</p>
