Recommended Test Procedure

  1. Verify current system date and time.
  2. Confirm backups exist before making changes.
  3. Print this page for offline reference.
  4. Review scripts that use two-digit years.
  5. Check folders, filenames, logs, and reports using YY formats.
  6. Test display output before and after 01/01/00.
  7. Notify the webmaster if any system believes it is 1900.

Known Risk Areas

Two-Digit Year Fields

Systems using 99, 00, or 01 without full century handling may sort, calculate, or archive dates incorrectly.

Example issue: 12/31/99 may roll over to 01/01/00, but some systems may interpret 00 as 1900 instead of 2000.

File and Folder Naming

Legacy archive generators may create folders using short date formats:

991231
000101
000102

Emergency Webmaster Notes

  1. Remain calm.
  2. Do not reboot all servers at once.
  3. Record the displayed date and time.
  4. Capture screenshots if possible.
  5. Restore from verified backup if required.
