Date Modifier
Synchronize with system's values: retrieves system's date and
time and uses these values to change the date and time of the file. To
change date & time stamps for creation, modification and last access
of the file, check the equivalent check boxes.
Cancel closes the dialog box without applying changes while
ok sets date and time as described from user.
Note: last access may have only a date stamp (restricted by the OS File System).
