Creation Date

Creation date is an attribute of a file that reflects the date and time when the file was created.

Displaying

You can display the file's creation date by:

• running DIRECTORY/FULL on it
• using the F$FILE_ATTRIBUTES() lexical: F$FILE_ATTRIBUTES(filespec,"CDT") returns the creation date and time

File Selection

Many DCL commands such as DIRECTORY offer a similar set of qualifiers for file selection. Since /CREATED is the default qualifier, you may simply use /BEFORE and /SINCE to select files created before or since a certain absolute time, delta time, a combination of these two, BOOT, LOGIN, TODAY (default), TOMORROW, or YESTERDAY.

Modifying

You may modify the creation date of a file with SET FILE/ATTRIBUTES=CREDATE.
