-.TH STRFTIME 3
-.SH NAME
-strftime \- generate formatted time information
-.SH SYNOPSIS
-.ft B
-.nf
-#include <sys/types.h>
-#include <time.h>
-.sp
-size_t strftime(char *s, size_t maxsize, const char *format,
-	const struct tm *timeptr);
-.SH DESCRIPTION
-The following description is transcribed verbatim from the December 7, 1988
-draft standard for ANSI C.
-This draft is essentially identical in technical content
-to the final version of the standard.
-.LP
-The
-.B strftime
-function places characters into the array pointed to by
-.B s
-as controlled by the string pointed to by
-.BR format .
-The format shall be a multibyte character sequence, beginning and ending in
-its initial shift state.
-The
-.B format
-string consists of zero or more conversion specifiers and ordinary
-multibyte characters.  A conversion specifier consists of a
-.B %
-character followed by a character that determines the behavior of the
-conversion specifier.
-All ordinary multibyte characters (including the terminating null
-character) are copied unchanged into the array.
-If copying takes place between objects that overlap the behavior is undefined.
-No more than
-.B maxsize
-characters are placed into the array.
-Each conversion specifier is replaced by appropriate characters as described
-in the following list.
-The appropriate characters are determined by the
-.B LC_TIME
-category of the current locale and by the values contained in the
-structure pointed to by
-.BR timeptr .
-.TP
-.B %a
-is replaced by the locale's abbreviated weekday name.
-.TP
-.B %A
-is replaced by the locale's full weekday name.
-.TP
-.B %b
-is replaced by the locale's abbreviated month name.
-.TP
-.B %B
-is replaced by the locale's full month name.
-.TP
-.B %c
-is replaced by the locale's appropriate date and time representation.
-.TP
-.B %d
-is replaced by the day of the month as a decimal number
-.RB ( 01 - 31 ).
-.TP
-.B %H
-is replaced by the hour (24-hour clock) as a decimal number
-.RB ( 00 - 23 ).
-.TP
-.B %I
-is replaced by the hour (12-hour clock) as a decimal number
-.RB ( 01 - 12 ).
-.TP
-.B %j
-is replaced by the day of the year as a decimal number
-.RB ( 001 - 366 ).
-.TP
-.B %m
-is replaced by the month as a decimal number
-.RB ( 01 - 12 ).
-.TP
-.B %M
-is replaced by the minute as a decimal number
-.RB ( 00 - 59 ).
-.TP
-.B %p
-is replaced by the locale's equivalent of the AM/PM designations associated
-with a 12-hour clock.
-.TP
-.B %S
-is replaced by the second as a decimal number
-.RB ( 00 - 60 ).
-.TP
-.B %U
-is replaced by the week number of the year (the first Sunday as the first
-day of week 1) as a decimal number
-.RB ( 00 - 53 ).
-.TP
-.B %w
-is replaced by the weekday as a decimal number
-.RB [ "0 " (Sunday)- 6 ].
-.TP
-.B %W
-is replaced by the week number of the year (the first Monday as the first
-day of week 1) as a decimal number
-.RB ( 00 - 53 ).
-.TP
-.B %x
-is replaced by the locale's appropriate date representation.
-.TP
-.B %X
-is replaced by the locale's appropriate time representation.
-.TP
-.B %y
-is replaced by the year without century as a decimal number
-.RB ( 00 - 99 ).
-.TP
-.B %Y
-is replaced by the year with century as a decimal number.
-.TP
-.B %Z
-is replaced by the time zone name or abbreviation, or by no characters if
-no time zone is determinable.
-.TP
-.B %%
-is replaced by
-.BR % .
-.LP
-If a conversion specifier is not one of the above, the behavior is
-undefined.
-.SH RETURNS
-If the total number of resulting characters including the terminating null
-character is not more than
-.BR maxsize ,
-the
-.B strftime
-function returns the number of characters placed into the array pointed to
-by
-.B s
-not including the terminating null character.
-Otherwise, zero is returned and the contents of the array are indeterminate.
-.SH NON-ANSI EXTENSIONS
-If
-.B SYSV_EXT
-is defined when the routine is compiled, then the following additional
-conversions will be available.
-These are borrowed from the System V
-.IR cftime (3)
-and
-.IR ascftime (3)
-routines.
-.TP
-.B %D
-is equivalent to specifying
-.BR %m/%d/%y .
-.TP
-.B %e
-is replaced by the day of the month,
-padded with a blank if it is only one digit.
-.TP
-.B %h
-is equivalent to
-.BR %b ,
-above.
-.TP
-.B %n
-is replaced with a newline character (\s-1ASCII LF\s+1).
-.TP
-.B %r
-is equivalent to specifying
-.BR "%I:%M:%S %p" .
-.TP
-.B %R
-is equivalent to specifying
-.BR %H:%M .
-.TP
-.B %T
-is equivalent to specifying
-.BR %H:%M:%S .
-.TP
-.B %t
-is replaced with a \s-1TAB\s+1 character.
-.PP
-If
-.B SUNOS_EXT
-is defined when the routine is compiled, then the following additional
-conversions will be available.
-These are borrowed from the SunOS version of
-.IR strftime .
-.TP
-.B %k
-is replaced by the hour (24-hour clock) as a decimal number
-.RB ( 0 - 23 ).
-Single digit numbers are padded with a blank.
-.TP
-.B %l
-is replaced by the hour (12-hour clock) as a decimal number
-.RB ( 1 - 12 ).
-Single digit numbers are padded with a blank.
-.PP
-If
-.B HPUX_EXT
-is defined when the routine is compiled, then the following additional
-conversions will be available.
-These are borrowed from the HP-UX version of
-.IR date .
-.TP
-.B %E
-The combined ``Emporer/Era'' name and year
-(same as
-.B %Y ).
-This is only available if
-.B POSIX2_DATE
-is
-.I not
-defined.
-.TP
-.B %F
-Same as
-.BR %B .
-(Marked as obsolescent in the HP-UX documentation.)
-.TP
-.B %N
-The ``Emporer/Era'' name.
-Typically, this is equivalent to the century
-(same as
-.B %C ).
-.TP
-.B %o
-The ``Emporer/Era'' year.
-Typically, this is equivalent to the year
-(same as
-.B %y ).
-.TP
-.B %z
-The timezone name or abbreviation.
-This is only available if
-.B MAILHEADER_EXT
-is
-.I not
-defined.
-.SH POSIX 1003.2 EXTENSIONS
-If
-.B POSIX2_DATE
-is defined, then all of the conversions available with
-.B SYSV_EXT
-and
-.B SUNOS_EXT
-are available, as well as the
-following additional conversions:
-.TP
-.B %C
-The century, as a number between 00 and 99.
-.TP
-.B %u
-is replaced by the weekday as a decimal number
-.RB [ "1 " (Monday)- 7 ].
-.TP
-.B %V
-is replaced by the week number of the year (the first Monday as the first
-day of week 1) as a decimal number
-.RB ( 01 - 53 ).
-The method for determining the week number is as specified by ISO 8601
-(to wit: if the week containing January 1 has four or more days in the
-new year, then it is week 1, otherwise it is the highest numbered
-week of the previous year (52 or 53)
-and the next week is week 1).
-.LP
-The text of the POSIX standard for the
-.I date
-utility describes
-.B %U
-and
-.B %W
-this way:
-.TP
-.B %U
-is replaced by the week number of the year (the first Sunday as the first
-day of week 1) as a decimal number
-.RB ( 00 - 53 ).
-All days in a new year preceding the first Sunday are considered to be
-in week 0.
-.TP
-.B %W
-is replaced by the week number of the year (the first Monday as the first
-day of week 1) as a decimal number
-.RB ( 00 - 53 ).
-All days in a new year preceding the first Monday are considered to be
-in week 0.
-.LP
-In addition, the alternate representations
-.BR %Ec ,
-.BR %EC ,
-.BR %Ex ,
-.BR %Ey ,
-.BR %EY ,
-.BR %Od ,
-.BR %Oe ,
-.BR %OH ,
-.BR %OI ,
-.BR %Om ,
-.BR %OM ,
-.BR %OS ,
-.BR %Ou ,
-.BR %OU ,
-.BR %OV ,
-.BR %Ow ,
-.BR %OW ,
-and
-.B %Oy
-are recognized, but their normal representations are used.
-.SH VMS EXTENSIONS
-If
-.B VMS_EXT
-is defined, then the following additional conversion is available:
-.TP
-.B %v
-The date in VMS format (e.g. 20-JUN-1991).
-.SH MAIL HEADER EXTENSIONS
-If
-.B MAILHEADER_EXT
-is defined, then the following additional conversion is available:
-.TP
-.B %z
-The timezone offset in a +HHMM format (e.g. the format necessary to
-produce RFC-822/RFC-1036 date headers).
-.SH ISO DATE FORMAT EXTENSIONS
-If
-.B ISO_DATE_EXT
-is defined, then all of the conversions available with
-.BR POSIX2_DATE,
-.BR SYSV_EXT,
-and
-.B SUNOS_EXT
-are available, as well as the
-following additional conversions:
-.TP
-.B %G
-is replaced by the year with century of the ISO week number (see
-.BR %V ,
-above) as a decimal number.
-.TP
-.B %g
-is replaced by the year without century of the ISO week number,
-as a decimal number
-.RB ( 00 - 99 ).
-.PP
-For example, January 1, 1993, is in week 53 of 1992. Thus, the year
-of its ISO week number is 1992, even though its year is 1993.
-Similarly, December 31, 1973, is in week 1 of 1974. Thus, the year
-of its ISO week number is 1974, even though its year is 1973.
-.SH SEE ALSO
-.IR time (2),
-.IR ctime (3),
-.IR localtime (3),
-.IR tzset (3)
-.SH BUGS
-This version does not handle multibyte characters or pay attention to the
-setting of the
-.B LC_TIME
-environment variable.
-.LP
-The ``appropriate'' values used for
-.BR %c ,
-.BR %x ,
-are
-.B %X
-are those specified by the 1003.2 standard for the POSIX locale.
-.SH CAVEATS
-The pre-processor symbol
-.B POSIX_SEMANTICS
-is automatically defined, which forces the code to call
-.IR tzset (3)
-whenever the
-.B TZ
-environment variable has changed.
-If this routine will be used in an application that will not be changing
-.BR TZ ,
-then there may be some performance improvements by not defining
-.BR POSIX_SEMANTICS .

-/*
- * strftime.c
- *
- * Public-domain implementation of ANSI C library routine.
- *
- * It's written in old-style C for maximal portability.
- * However, since I'm used to prototypes, I've included them too.
- *
- * If you want stuff in the System V ascftime routine, add the SYSV_EXT define.
- * For extensions from SunOS, add SUNOS_EXT.
- * For stuff needed to implement the P1003.2 date command, add POSIX2_DATE.
- * For VMS dates, add VMS_EXT.
- * For an RFC822 time format, add MAILHEADER_EXT.
- * For ISO week years, add ISO_DATE_EXT.
- * For complete POSIX semantics, add POSIX_SEMANTICS.
- *
- * The code for %c, %x, and %X now follows the 1003.2 specification for
- * the POSIX locale.
- * This version ignores LOCALE information.
- * It also doesn't worry about multi-byte characters.
- * So there.
- *
- * This file is also shipped with GAWK (GNU Awk), gawk specific bits of
- * code are included if GAWK is defined.
- *

-Hi Arnold,
-in a process of fixing of strftime() in libraries on Atari ST I grabbed
-some pieces of code from your own strftime.  When doing that it came
-to mind that your weeknumber() function compiles a little bit nicer
-in the following form:
-/*
- * firstweekday is 0 if starting in Sunday, non-zero if in Monday
- */
-{
-    return (timeptr->tm_yday - timeptr->tm_wday +
-	    (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
-}
-How nicer it depends on a compiler, of course, but always a tiny bit.
-
-   Cheers,
-   Michal
