			CloneDate.exe,  Version 1.00
```

			Modify the LastModified date (timestamp) of the target file(s) to

			match the specified source file's timestamp

```
 
```

			Usage:    CloneDate.exe  sourcefile  targetfiles  [ /Debug ]

```
 
```

			Where:    sourcefile     is the file whose timestamp is to be cloned

			          targetfiles    are the files whose timestamp are to be modified

			                         (single filespec, wildcards * and ? are allowed)

			          /Debug         displays file name and timestamps before and

			                         after modification for each matching file

```
 
```

			Example:  CloneDate.exe C:\boot.ini C:\test.log

			          will change C:\test.log's timestamp to match C:\boot.ini's

```
 
```

			Notes:    Target filespec may include sourcefile (sourcefile will be skipped).

			          Always be careful when using wildcards; they may also return matching

			          "short" (8.3) file names (for backwards compatibility with FAT16).
