CTIME(3P) POSIX Programmer's Manual CTIME(3P)
PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
ctime, ctime_r -- convert a time value to a date and time string
SYNOPSIS
#include <time.h>
char *ctime(const time_t *clock);
char *ctime_r(const time_t *clock, char *buf);
DESCRIPTION
For ctime(): The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.
The ctime() function shall convert the time pointed to by clock, representing time in seconds since the Epoch, to local time in the form of
a string. It shall be equivalent to:
asctime(localtime(clock))
The asctime(), ctime(), gmtime(), and localtime() functions shall return values in one of two static objects: a broken-down time structure
and an array of char. Execution of any of the functions may overwrite the information returned in either of these objects by any of the
other functions.
The ctime() function need not be thread-safe.
The ctime_r() function shall convert the calendar time pointed to by clock to local time in exactly the same form as ctime() and put the
string into the array pointed to by buf (which shall be at least 26 bytes in size) and return buf.
Unlike ctime(), the ctime_r() function is not required to set tzname. If ctime_r() does not set tzname, it shall not set daylight and
shall not set timezone.
RETURN VALUE
The ctime() function shall return the pointer returned by asctime() with that broken-down time as an argument.
Upon successful completion, ctime_r() shall return a pointer to the string pointed to by buf. When an error is encountered, a null pointer
shall be returned.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
These functions are included only for compatibility with older implementations. They have undefined behavior if the resulting string would
be too long, so the use of these functions should be discouraged. On implementations that do not detect output string length overflow, it
is possible to overflow the output buffers in such a way as to cause applications to fail, or possible system security violations. Also,
these functions do not support localized date and time formats. To avoid these problems, applications should use strftime() to generate
strings from broken-down times.
Values for the broken-down time structure can be obtained by calling gmtime() or localtime().
The ctime_r() function is thread-safe and shall return values in a user-supplied buffer instead of possibly using a static data area that
may be overwritten by each call.
Attempts to use ctime() or ctime_r() for times before the Epoch or for times beyond the year 9999 produce undefined results. Refer to asc-
time().
RATIONALE
The standard developers decided to mark the ctime() and ctime_r() functions obsolescent even though they are in the ISO C standard due to
the possibility of buffer overflow. The ISO C standard also provides the strftime() function which can be used to avoid these problems.
FUTURE DIRECTIONS
These functions may be removed in a future version.
