time_t icaltime_as_timet ( const struct icaltimetype  tt  ) 

Return the time as seconds past the UNIX epoch.

Return the time as seconds past the UNIX epoch

While this function is not currently deprecated, it probably won't do what you expect, unless you know what you're doing. In particular, you should only pass an icaltime in UTC, since no conversion is done. Even in that case, it's probably better to just use icaltime_as_timet_with_zone().
