The /D option of the XCOPY command does not specify local time. Instead, XCOPY /D copies all files created GMT 12:00 A.M. or later on the date specified. XCOPY /D: does not convert the entered date from local time to universal time before doing the copy.

For example, if the system is set for PDT (-7) and the following files exist in the Test folder
   TEST1.TMP  07/27/98  04:02p
   TEST2.TMP  07/27/98  05:02p
   TEST3.TMP  07/28/98  12:01a
   TEST4.TMP  07/28/98  12:02a

and the following command is entered

xcopy *.tmp d:\test\*.* /D:07-28-98
the following files are copied:

   TEST2.TMP  07/27/98  05:02p
   TEST3.TMP  07/28/98  12:01a
   TEST4.TMP  07/28/98  12:02a


XCOPY compares the date provided in the /D switch against the file date to determine which files to copy. In Windows NT, the file date is stored in Universal Time (GMT).
