Function Details : ctime

char *ctime(const time_t * timer) ;

Return Type : char *

String pointer (array of characters)
Read about return values of ctime function .

1st Parameter Type : const time_t *

A pointer to a constant `time_t` object, representing time as the number of seconds since the epoch (00:00:00 UTC, January 1, 1970). The data it points to cannot be modified.

1st Parameter

Pointer to a `time_t` object representing the time in seconds since the epoch

The ctimefunction in C language Converts the calendar time to a local time string.
The ctime function converts the calendar time pointed to by timer into a string of the form 'Www Mmm dd hh:mm:ss yyyy\n', where Www is the weekday, Mmm is the month in letters, dd is the day of the month, hh:mm:ss is the time, and yyyy is the year. The string is in local time. This function is equivalent to asctime(localtime(timer)). Note that it's not thread-safe as it returns a pointer to a static buffer.
The ctimefunction takes 1 parameter:
  • •
    const time_t * `timer`: Pointer to a `time_t` object representing the time in seconds since the epoch
Converts the time value pointed to by `timer` into a human-readable string in the format 'Day Mon DD HH:MM:SS YYYY\n'. The string is stored in a static buffer and overwritten by subsequent calls.
The ctime function return value :
  • Returns a pointer to a string containing the date and time information in a human-readable format
  • This pointer is to a static buffer that may be overwritten by subsequent calls to ctime

Output

This example demonstrates the basic usage of the `ctime` function. It gets the current time using time() and then converts it to a readable string using ctime().
