value (integer seconds) and as a tm structure (year, month, day, hour, minute, second). The two values are kept in synch.<p>Implementation notes: The functions mktime() and localtime() are used to convert between time_t and tm. Although it seems as if this operating on "local" time, it isn't really; it is just a time value. These functions are used because they are the only bidirectional conversion functions exposed by the ANSI C library - the gmtime() function converts time_t to tm more directly, but there is no corresponding method to convert directly from tm to time_t. <p><hr><h2>Member Function Documentation</h2><a class="anchor" name="5eb40c2663303fd3e40afab66a49e41a"></a><!-- doxytag: member="vtTime::SetDate" ref="5eb40c2663303fd3e40afab66a49e41a" args="(int year, int month, int day)" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">void vtTime::SetDate </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">int </td> <td class="mdname" nowrap> <em>year</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>month</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>day</em></td> </tr> <tr> <td class="md"></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p>Set the date components of a vtTime value.<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"></td><td valign="top"><em>year</em> </td><td>E.g. 2001. </td></tr> <tr><td valign="top"></td><td valign="top"><em>month</em> </td><td>in the range of 1 to 12. </td></tr> <tr><td valign="top"></td><td valign="top"><em>day</em> </td><td>in the range of 1 to 31. </td></tr> </table></dl> </td> </tr></table><hr size="1"><address style="align: right;"><small>Generated on Mon Jan 14 14:40:55 2008 for vtdata library by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.4.5 </small></address></body></html>⌨️ 快捷键说明
