..usw...

Ich weiss, sieht ziemlich kompliziert aus. Ist aber halt so. Wünsche mir PHP


@nuc:

danke, genau die seite hatte ich auch schon. aber leider muss ich gerade sozusagen meine strings bzw. int in dieses time_t-format umwandeln.


Converting a string to a time_t is harder, because of the wide variety of date and time formats which should be parsed. Some systems provide a strptime function; another popular routine is partime (widely distributed with the RCS package), but these are less likely to become standardized
