<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>You can specify
the date to be used on your system. The date includes the month, day, and
year. The system supports dates that range from August 24, 1928 to July 6,
2053. If your system is not using the Gregorian calendar, the day of the week
may not be set correctly. If the year (QYEAR) system value changes to a different
century, the system automatically updates the century (QCENTURY) system value.</p>
<p>In
the iSeries Navigator
interface, the system date (QDATE) and time of day (QTIME) system values have
not changed. However, they are combined into one system value in the character-based
interface, QDATETIME. If you are accessing the date or time system value using
the character-based interface, use QDATETIME rather than QDATE or QTIME. In
the character-based interface, QDATE and QTIME are still accessible so you
can access the date and time values separately, if needed. Use the QDATE and
QTIME system values to retrieve values, and use the QDATETIME system value
to set the date, time, or both. This ensures that the system values do not
conflict with each other.</p>
</div>
<div class="section"><h4 class="sectiontitle">Where can I get more information about this system value?</h4><p>To
learn more, go to the date and time system values overview topic. If you are
looking for a specific system value or category of system values, try using
the i5/OS system
value finder.</p>
