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 IEEE Std 1003.1-2001 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 reentrant. A function that is not required to be reentrant is not required to 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 thread-safe version ctime_r() is not required to set tzname.
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
Values for the broken-down time structure can be obtained by calling gmtime() or localtime(). The ctime() function is included for compati-
bility with older implementations, and does not support localized date and time formats. Applications should use the strftime() function
to achieve maximum portability.
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.
RATIONALE
None.
FUTURE DIRECTIONS
None.
