Converts local calendar time to a time since epoch as a time_t object, ignoring the values of time->tm_wday and time->yday. The values of other components of time are not restricted to their usual ranges. A negative value of time->tm_isdst causes mktime to attempt to determine if Daylight Saving Time was in effect.
