Unless the application has called <code>setlocale</code>, the output will be in the default locale, of length 24 and of the form ‘<samp><span class="samp">Sat Aug 19 18:13:14 1995</span></samp>’. In other locales, a longer string may result. <p>This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit. <br><dt><em>Standard</em>:<dd>GNU extension <br><dt><em>Class</em>:<dd>Subroutine, function <br><dt><em>Syntax</em>:<dd> <p><table summary=""><tr align="left"><td valign="top" width="80%"><code>CALL CTIME(TIME, RESULT)</code>. <br></td></tr><tr align="left"><td valign="top" width="80%"><code>RESULT = CTIME(TIME)</code>. <br></td></tr></table> <br><dt><em>Arguments</em>:<dd> <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>TIME</var> </td><td valign="top" width="70%">The type shall be of type <code>INTEGER</code>. <br></td></tr><tr align="left"><td valign="top" width="15%"><var>RESULT</var> </td><td valign="top" width="70%">The type shall be of type <code>CHARACTER</code> and of default kind.
