mktime
From cppreference.com
| Defined in header <time.h>
|
||
Converts local calendar time to a time since epoch as a time_t object. time->tm_wday and time->tm_yday are ignored. The values in time are not checked for being out of range.
A negative value of time->tm_isdst causes mktime to attempt to determine if Daylight Saving Time was in effect.
If the conversion is successful, the time object is modified. All fields of time are updated to fit their proper ranges. time->tm_wday and time->tm_yday are recalculated using information available in other fields.
