FUNCTION
<<asctime>>---format time as string

INDEX
	asctime
INDEX
	_asctime_r

ANSI_SYNOPSIS
	#include <time.h>
	char *asctime(const struct tm *<[clock]>);
	char *_asctime_r(const struct tm *<[clock]>, char *<[buf]>);

TRAD_SYNOPSIS
	#include <time.h>
	char *asctime(<[clock]>)
	struct tm *<[clock]>;
	char *asctime_r(<[clock]>)
	struct tm *<[clock]>;
	char *<[buf]>;

DESCRIPTION
Format the time value at <[clock]> into a string of the form
. Wed Jun 15 11:38:07 1988\n\0
The string is generated in a static buffer; each call to <<asctime>>
overwrites the string generated by previous calls.

PORTABILITY
ANSI C requires <<asctime>>.
