|

| 12 | <h3>Description</h3>
|
|---|
| 13 | <p>Changes the modification time of a file and possibly creates it at
|
|---|
| 14 | the same time. In addition to working with a single file, this Task
|
|---|
| 15 | can also work a <a href="../CoreTypes/fileset.html">Fileset</a> (which
|
|---|
| 16 | also includes directories).</p>
|
|---|
| 17 | <p>For JDK 1.1 only the creation of new files with a modification time
|
|---|
| 18 | of now works, all other cases will emit a warning.</p>

|
|---|
| 52 | <p>creates <code>myfile</code> if it doesn't exist and changes the
|
|---|
| 53 | modification time to Jun, 28 2000 2:02 pm (14:02 for those used to 24
|
|---|
| 54 | hour times).</p>

|
|---|
| 56 | <fileset dir="src_dir"/>

|
|---|
| 63 | hour times), if the filesystem allows a precision of one second - a
|
|---|
| 64 | time close to it otherwise.</p>
