C++ ctime asctime() Function
Example
Display the date and time from a tm structure:
time_t timestamp;
time(×tamp);
struct tm * myTime = localtime(×tamp);
cout << asctime(myTime);
Definition and Usage
The asctime() function returns a pointer to a C-style string representing the date and time of a tm structure. The returned string has the format WWW MMM DD HH:mm:ss YYYY (for example: "Sun Dec 17 21:34:26 2023"). For more control over date and time formatting, see the strftime() function.
The asctime() function is defined in the <ctime> header file.
Tip: Use the gmtime() or localtime() function to get a tm structure from a timestamp.
Note: Because the return value is a pointer, the value of the string may be changed by additional calls to asctime() or ctime().
