File times on Windows 2000 are stored as a FILETIME value. This is a 64-bit value that represents the number of 100-nanosecond intervals since January 1, 1601 (UTC). Windows 2000 also supports time-zone
adjustments. Time-zone adjustments are accomplished by adding a time-zone offset to the UTC time to compute local time. Time-zone offsets range from -12 hours (Eniwetok, Kwajalein) to +13 hours (Nuku'alofa).
If the system time is set to January 1, 1601, 12:00am UTC, and a file is created, the various file times that are saved for the file are a FILETIME that is equal to zero (0). If a user then issues a dir command to list the file, the UTC time from the file is read, and the local time-zone adjustment is added. If the local time-zone adjustment is positive, a valid FILETIME is
computed. However, if the computer is configured for a time zone with a negative time zone adjustment, an invalid FILETIME value is computed.
This invalid FILETIME value results in the dir command displaying an invalid and obviously incorrect date and time for the file. For example:
D:\1601Date>dir
Volume in drive D is Data
Volume Serial Number is B00D-F582
Directory of D:\1601Date
12/15/2001 03:26 PM <DIR> .
12/15/2001 03:26 PM <DIR> ..
5252/00/23678 58848:92 15 test.txt
1 File(s) 15 bytes
2 Dir(s) 3,874,045,952 bytes free
CAUSE
This problem can occur because the dir command incorrectly assumes that the Win32 FileTimeToLocalFileTime API would always return a valid FILETIME. If the FILETIME is Jan 1, 1601 (a 64-bit value of zero), and the time-zone adjustment is negative, this assumption is incorrect.
