C++ ctime ctime() Function

❮ ctime Functions

Example

Display the date and time of a timestamp as a string:

time_t timestamp;
time(&timestamp);
cout << ctime(&timestamp);
Try it Yourself »

Definition and Usage

The ctime() function returns a pointer to a C-style string representing the date and time of a time_t timestamp. 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 ctime() function is defined in the <ctime> header file.

Note: Use the time() or mktime() functions to create 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().

Syntax

ctime(time_t * timestamp);

The time_t data type represents a number.

Parameter Values

Parameter Description
time Required. A time_t timestamp representing the date and time to be represented.

Technical Details

Returns: A char type pointer to a C-style string containing a representation of the date and time.
