int tm_sec;
int tm_min;
int tm_hour;
int tm_mday;
int tm_mon;
int tm_year;
int tm_wday;
int tm_yday;
int tm_isdst;
|
The meaning of each is:
| Member | Meaning | Range |
|---|
| tm_sec | seconds after the minute | 0-61* |
| tm_min | minutes after the hour | 0-59 |
| tm_hour | hours since midnight | 0-23 |
| tm_mday | day of the month | 1-31 |
| tm_mon | months since January | 0-11 |
| tm_year | years since 1900 | |
| tm_wday | days since Sunday | 0-6 |
| tm_yday | days since January 1 | 0-365 |
| tm_isdst | Daylight Saving Time flag | |
The Daylight Saving Time flag (tm_isdst) is greater than zero if Daylight Saving Time is in effect, zero if Daylight Saving Time is not in effect, and less than zero if the information is not available.
* tm_sec is generally 0-59. Extra range to accommodate for leap seconds in certain systems.
