| <h2><a name="touch">Touch</a></h2> |
| <h3>Description</h3> |
| <p>Changes the modification time of a file and possibly creates it at |
| the same time. In addition to working with a single file, this Task |
| can also work a <a href="../CoreTypes/fileset.html">Fileset</a> (which |
| also includes directories).</p> |
| <p>For JDK 1.1 only the creation of new files with a modification time |
| of now works, all other cases will emit a warning.</p> |
| <h3>Parameters</h3> |
| <table border="1" cellpadding="2" cellspacing="0"> |
| <tr> |
| <td valign="top"><b>Attribute</b></td> |
| <td valign="top"><b>Description</b></td> |
| <td align="center" valign="top"><b>Required</b></td> |
| </tr> |
| <tr> |
| <td valign="top">file</td> |
| <td valign="top">the name of the file</td> |
| <td valign="top" align="center">unless a nested fileset element |
| has been specified.</td> |
| </tr> |
| <tr> |
| <td valign="top">millis</td> |
| <td valign="top">specifies the new modification time of the file |
| in milliseconds since midnight Jan 1 1970</td> |
| <td valign="top" align="center">No</td> |
| </tr> |
| <tr> |
| <td valign="top">datetime</td> |
| <td valign="top">specifies the new modification time of the file |
| in the format MM/DD/YYYY HH:MM AM_or_PM.</td> |
| <td valign="top" align="center">No</td> |
| </tr> |
| </table> |
| <p>If both <code>millis</code> and <code>datetime</code> are omitted |
| the current time is assumed.</p> |
| <h3>Examples</h3> |
| <pre> <touch file="myfile"/></pre> |
| <p>creates <code>myfile</code> if it doesn't exist and changes the |
| modification time to the current time.</p> |
| <pre> <touch file="myfile" datetime="06/28/2000 2:02 pm"/></pre> |
| <p>creates <code>myfile</code> if it doesn't exist and changes the |
| modification time to Jun, 28 2000 2:02 pm (14:02 for those used to 24 |
| hour times).</p> |
| <pre> <touch datetime="09/10/1974 4:30 pm"> |
| <fileset dir="src_dir"/> |
| </touch></pre> |

| found in <code>src_dir</code>. </p> |
