La última vez que había guardado el archivo fue el 1 de enero de 1601: ¿qué es esto?, ¿por qué? Esto es más fuerte que lo de los Autobuses en Barcelona que viajan al pasado, y es que en 1601 me parece que todavía no existía la versión de Macrochoft que utilizo.
Pues bien: como siempre, la respuesta no está en el viento, sino en Wikipedia:
Year 1601 (MDCI) was a common year starting on Monday (link will display the full calendar) of the Gregorian calendar and a common year starting on Thursday of the 10-day slower Julian calendar. January 1 of this year (1601-01-01) is used as the base of file dates[1] and of Active Directory Logon dates[2] by Microsoft Windows. It is also the date from which ANSI dates are counted and were adopted by the American National Standards Institute for use with COBOL and other computer languages. This epoch is the beginning of the latest 400-year cycle by which leap-years are calculated in the Gregorian calendar. The last year of this cycle is the only one divisible by 100 that is a leap-year, which is the year 2000, and which is followed by a new 400-year cycle beginning with 2001. 32-bit versions of the Microsoft Windows operating system count units of one hundred nanoseconds from this epoch.[3]
