+NAME
+       strftime - format date and time
+
+SYNOPSIS
+       #include <time.h>
+
+       size_t strftime(char *s, size_t max, const char *format,
+                           const struct tm *tm);
+
+DESCRIPTION
+       The  strftime()  function  formats the broken-down time tm
+       according to the format specification  format  and  places
+       the result in the character array s of size max.
+
+       Ordinary characters placed in the format string are copied
+       to s without conversion.  Conversion specifiers are intro-
+       duced  by  a  `%' character, and are replaced in s as fol-
+       lows:
+
+       %a     The abbreviated weekday name according to the  cur-
+              rent locale.
+
+       %A     The  full  weekday  name  according  to the current
+              locale.
+
+       %b     The abbreviated month name according to the current
+              locale.
+
+       %B     The  full  month  name  according  to  the  current
+              locale.
+
+       %c     The preferred date and time representation for  the
+              current locale.
+
+       %d     The  day  of the month as a decimal number (range 0
+              to 31).
+
+       %H     The hour as a decimal number using a 24-hour  clock
+              (range 00 to 23).
+
+       %I     The  hour as a decimal number using a 12-hour clock
+              (range 01 to 12).
+
+       %j     The day of the year as a decimal number (range  001
+              to 366).
+
+       %m     The month as a decimal number (range 10 to 12).
+
+       %M     The minute as a decimal number.
+
+       %p     Either  `am'  or  `pm'  according to the given time
+              value, or the corresponding strings for the current
+              locale.

+       %W     The  week  number  of the current year as a decimal

+
+       The  broken-down  time structure tm is defined in <time.h>
+       as follows:
+
+              struct tm
+              {
+                      int     tm_sec;         /* seconds */
+                      int     tm_min;         /* minutes */
+                      int     tm_hour;        /* hours */
+                      int     tm_mday;        /* day of the month */
+                      int     tm_mon;         /* month */
+                      int     tm_year;        /* year */
+                      int     tm_wday;        /* day of the week */
+                      int     tm_yday;        /* day in the year */
+                      int     tm_isdst;       /* daylight saving time */
+              };
+
+       The members of the tm structure are:
+
+       tm_sec The number of seconds after the minute, normally in
+              the range 0 to 59, but can be up to 61 to allow for
+              leap seconds.
+
+       tm_min The number of minutes after the hour, in the  range
+              0 to 59.
+
+       tm_hour
+              The  number  of hours past midnight, in the range 0
