std::ctime - cppreference.com (original) (raw)
Converts given time since epoch to a calendar local time and then to a textual representation, as if by calling std::asctime(std::localtime(time)). The resulting string has the following format:
Www Mmm dd hh:mm:ss yyyy\n
Www- the day of the week (one ofMon,Tue,Wed,Thu,Fri,Sat,Sun).Mmm- the month (one ofJan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec).dd- the day of the month.hh- hours.mm- minutes.ss- seconds.yyyy- years.
The function does not support localization.
[edit] Parameters
| time | - | pointer to a std::time_t object specifying the time to print |
|---|
[edit] Return value
Pointer to a static null-terminated character string holding the textual representation of date and time. The string may be shared between std::asctime and std::ctime, and may be overwritten on each invocation of any of those functions.
[edit] Notes
This function returns a pointer to static data and is not thread-safe. In addition, it modifies the static std::tm object which may be shared with std::gmtime and std::localtime. POSIX marks this function obsolete and recommends std::strftime instead.
The behavior may be undefined for the values of std::time_t that result in the string longer than 25 characters (e.g. year 10000).
