Incorrect date stamps

I can’t figure out why my backups are not dated correctly. When I backed up my days’s writing onto an external and internal drive both of them indicated a date three days earlier than today’s date. Can someone help? Thanks!

Do you mean the date that is added to the backup file’s name? Or are you talking about the date that your computer shows for the list of files?

Thanks for responding rdale. No, I’m not referring to the file’s name but to the date listed in the “Date Modified” column in the internal/external drive’s listing of backups.

How odd. I’m assuming the Mac OS assigns the modified date?

Have you checked that the zipped backup does in fact contain the correct/latest version of your project?
