<p><strong>Message file library name.</strong>&nbsp;&nbsp;
The name of the library containing the message file used to retrieve the Standard Time message and the Daylight Saving Time message. The field may contain *LIBL which means that the library list is searched to locate the message file. The library name is left-justified and padded with blanks on the right. If the message file name specifies *NONE, this field returns blanks.</p>
<p><strong>Message file name.</strong>&nbsp;&nbsp;
The name of the message file used to retrieve the Standard Time message and the Daylight Saving Time message. The message file name is left-justified and padded with blanks on the right. If a message was not specified when the time zone description was created or last changed, this field returns *NONE.</p>
<p><strong>Number of time zone descriptions available.</strong>&nbsp;&nbsp;
The number of time zone descriptions that match the time zone description name specified on the call to this API. This is the number of time zone descriptions which the caller of the API has *USE authority to.</p>
<p><strong>Number of time zone descriptions returned.</strong>&nbsp;&nbsp;
The number of time zone descriptions returned in the receiver variable.</p>
<p><strong>Offset from UTC.</strong>&nbsp;&nbsp;
The time difference, in minutes, between this time zone and Coordinated Universal Time (UTC). This value is subtracted from local time to obtain UTC time. A negative difference indicates that the time zone is west of UTC and a positive difference indicates that the time zone is east of UTC.</p>
<p><strong>Offset to time zone descriptions.</strong>&nbsp;&nbsp;
The offset in bytes from the beginning of the receiver variable to the first time zone description.</p>
<p><strong>Reserved.</strong>&nbsp;&nbsp;
An unused field.</p>
<p><strong>Standard Time abbreviated name.</strong>&nbsp;&nbsp;
The abbreviated name used with the time zone when Daylight Saving Time is not being observed. If the time zone description uses a message to specify the abbreviated name and the message cannot be retrieved, this field returns *N. This can occur when the caller of the API is not authorized to the message file or its library, the message file cannot be found or the message does not exist in the specified message file.</p>
<p><strong>Standard Time full name.</strong>&nbsp;&nbsp;
The full name of the time zone when Daylight Saving Time is not being observed. If the time zone description uses a message to specify the full name and the message cannot be retrieved, this field returns *N. This can occur when the caller of the API is not authorized to the message file or its library, the message file cannot be found or the message does not exist in the specified message file.</p>
<p><strong>Standard Time message.</strong>&nbsp;&nbsp;
The message that contains the abbreviated and full names of the time zone when Daylight Saving Time is not being observed. If a message was not specified when the time zone description was created or last changed, this field returns *NONE.</p>
<p><strong>Text description.</strong>&nbsp;&nbsp;
The user text, if any, used to briefly describe the time zone description.</p>
<p><strong>Time zone description name.</strong>&nbsp;&nbsp;
The name of the time zone description object.</p>
<p><strong>TZ string.</strong>&nbsp;&nbsp;
A null-terminated character string that describes the time zone in a format compatible with industry standards. The returned string may be used to set i5/OS PASE environment variable TZ, and has this format (spaces inserted for readability):</p>
<pre>
std offset dst offset , start/time , end/time
</pre>
<p>An example of a TZ value for time zone QN0600CST (USA Central time) is "CST6CDT,M4.1.0,M10.5.0". Daylight Saving Time specifications (dst, offset, start/time, and end/time) are omitted if the time zone does not use Daylight Saving Time.</p>
<dl>
<dt><tt>std</tt></dt>
<dd>This is the <strong>Standard Time abbreviated name</strong> string, stripped of trailing blanks and replacing any characters not allowed by standards with asterisks (nulls, decimal digits, plus sign, minus sign, comma, and leading colon).</dd>
<dt><tt>offset</tt></dt>
<dd>Hours and minutes behind Coordinated Universal Time (UTC). Minutes are omitted if the time zone is an integral number of hours behind UTC. <tt>offset</tt> is formatted as hh:mm if minutes are included, and has a leading minus sign if the value is negative. A negative value indicates the time zone is east of UTC, which is the opposite of the <strong>Offset from UTC</strong> field (in format <strong>RTMZ0100</strong>).</dd>
<dt><tt>dst</tt></dt>
<dd>This is the <strong>Daylight Saving Time abbreviated name</strong> string, stripped of trailing blanks and replacing any characters not allowed by standards with asterisks (nulls, decimal digits, plus sign, minus sign, comma, and leading colon).</dd>
<dt><tt>start/time</tt></dt>
<dd>Specifies when Daylight Saving Time starts. <tt>start</tt> includes the month (1-12), week number (1-5), and day (0-6, for Sunday-Saturday) in the form <tt>Mm.n.d</tt>. <tt>time</tt> is formatted as <tt>hh:mm:ss</tt>, but is omitted if Daylight Saving Time starts at 2:00:00.</dd>
<dt><tt>end/time</tt></dt>
<dd>Specifies when Daylight Saving Time ends. <tt>end</tt> includes the month (1-12), week number (1-5), and day (0-6, for Sunday-Saturday) in the form <tt>Mm.n.d</tt>. <tt>time</tt> is formatted as <tt>hh:mm:ss</tt>, but is omitted if Daylight Saving Time ends at 2:00:00.</dd>
