[Bearbeiten] Notes
Die Codierung der Kalenderzeit in std::time_t ist unbegrenzt, aber die meisten Systeme entsprechen POSIX specification und einen Wert zurückgeben integraler Typ, der die Anzahl der Sekunden seit der Epoche. Implementierungen, in denen std::time_t ist ein 32-Bit-Integer (viele historische Implementierungen) scheitern im Jahr 2038 .
Original:
The encoding of calendar time in std::time_t is unspecified, but most systems conform to POSIX specification and return a value of integral type holding the number of seconds since the Epoch. Implementations in which std::time_t is a 32-bit signed integer (many historical implementations) fail in the year 2038.
