Touch

Changes the modification time of a file and possibly creates it at the same time.

For JDK 1.1 only the creation of new files with a modification time of now works, all other cases will emit a warning.

Attribute	Description	Required
file	the name of the file	Yes
millis	specifies the new modification time of the file in milliseconds since midnight Jan 1 1970	No
datetime	specifies the new modification time of the file in the format MM/DD/YYYY HH:MM AM_or_PM.	No

If both millis and datetime are omitted the current time is assumed.

  <touch file="myfile"/>

creates myfile if it doesn't exist and changes the modification time to the current time.

  <touch file="myfile" datetime="06/28/2000 2:02 pm"/>

creates myfile 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).
