The tm_year member of struct tm hold the number of years since 1900,
so you have to add 1900 to it in order to get the current year.

Also, you have to add 1 to tm_mon, since January is 0, February is 1,
etc.

That said, strftime() may be a better choice to get a textual
representation of timestamps.
