SYNOPSIS |
#include <time.h> char *ctime(const time_t *timep);
DESCRIPTION |
ctime
converts a
time_t
value (as returned by
the
time
function) to a printable character
string and returns the address of the first character of the string. The
string has the form
wkd mon dd hh:mm:ss yyyy\n
, for example,
Thu Oct 10 16:49:07 1985\n
. The length of the string is always 25. (The day of the month is
padded on the left with blanks to two characters if necessary; the hours,
minutes, and seconds are padded with 0s.)
ctime
is affected
by time zone information contained in the TZ environment variable.
RETURN VALUE |
ctime
returns a pointer to the formatted local date and time.
CAUTION |
The pointer returned by
ctime
may reference
static
storage,
which may be overwritten by the next call to
asctime
or
ctime
.
IMPLEMENTATION |
ctime(timep)
is implemented as
asctime(localtime(timep))
.
EXAMPLE |
#include <time.h> #include <stdio.h> main () { time_t timeval; time(&timeval); printf("The current time and date are: %s", ctime(&timeval)); }
