<p>The Get Offset from Universal Time Coordinated to Local Time (CEEUTCO) API
|
||
|
|
provides three values representing the current offset from Universal Time
|
||
|
|
Coordinated (UTC) to local system time. <em>Offset_seconds</em> can be used
|
||
|
|
with CEEUTC to calculate local date and time. <em>Offset_hours</em> and <em>
|
||
|
|
offset_minutes</em> express the offset from UTC in terms of hours and
|
||
|
|
minutes.</p>
|
||
|
|
|
||
|
|
<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
|
||
|
|
<!-- Instead, use the commented out coding below to indicate NONE. -->

<h3>Authorities and Locks</h3>

|
<dl>
|
||
|
|
<dt><strong>offset_hours (output)</strong></dt>
|
||
|
|
|
||
|
|
<dd>A 32-bit binary integer representing the offset from UTC to local time, in
|
||
|
|
hours; for Pacific Standard Time <em>offset_hours</em> is -8. The range for
|
||
|
|
<em>offset_hours</em> is -12 to -13, where +13 is Daylight Savings Time in the
|
||
|
|
+12 time zone. If local time offset is not available, <em>offset_hours</em> is
|
||
|
|
set to 0 and CEEUTCO ends with a nonzero feedback code.<br>
|
||
|
|
<br>
|
||
|
|
</dd>
|
||
|
|
|
||
|
|
<dt><strong>offset_minutes (output)</strong></dt>
|
||
|
|
|
||
|
|
<dd>A 32-bit binary integer representing the number of additional minutes that
|
||
|
|
local time is ahead of, or behind, UTC. The range for <em>offset_minutes</em>
|
||
|
|
is 0 to 59. If the local time offset is not available, <em>offset_minutes</em>
|
||
|
|
is set to 0 and CEEUTCO ends with a nonzero feedback code.<br>
|
||
|
|
<br>
|
||
|

</dd>
|
||
|
|
|
||
|
|
<dt><strong>offset_seconds (output)</strong></dt>
|
||
|
|
|
||
|
|
<dd>A 64-bit double floating point (output) number representing the offset from
|
||
|
|
UTC to local time, in seconds. For example, Pacific Standard Time is eight
|
||
|
|
hours behind UTC. If the system is in the Pacific time zone during standard
|
||
|
|
time, CEEUTCO returns -28 800 (-8 * 60 * 60). The range for <em>
|
||
|
|
offset_seconds</em> is -43 200 to +46 800. If the local time offset
|
||
|
|
is not available from the system, <em>offset_seconds</em> is set to 0 and
|
||
|
|
CEEUTCO ends with a nonzero feedback code.</dd>

<dl>

<dt><strong>fc (output)</strong></dt>

<dd>A 12-byte feedback code passed by reference. If specified as an argument,

|
|
feedback information (a condition token) is returned to the calling procedure.
|

If not specified and the requested operation was not successfully completed,

the condition is signaled to the condition manager.</dd>

<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The values returned by CEEUTCO and CEEUTC can be used together to calculate
|
||
|
|
the local date and time.</li>
|
||
|
|
|
||
|
|
<li>The CEEDATM API can be used to convert number of seconds to character
|
||
|
|
timestamp.<br>
|
