Fix HFS time #266

Closed fuzz6001 closed 5 months ago

fuzz6001 commented 5 months ago 
tm* ctime = gmtime(&creationTime);
ctime->tm_year -= 66;

Because of the leap year discrepancy, this method cannot be used to obtain the correct day. The year 1904 (Mac/HFS epoch) is a leap year, but 1970 (Unix epoch) is not.

In addition, a minor bug in the last backup date has been fixed.

e.g.

HFS time Correct date/time Current DIC
