-DESCRIPTION
-<<strftime>> converts a <<struct tm>> representation of the time (at
-<[timp]>) into a null-terminated string, starting at <[s]> and occupying
-no more than <[maxsize]> characters.
-
-You control the format of the output using the string at <[format]>.
-<<*<[format]>>> can contain two kinds of specifications: text to be
-copied literally into the formatted string, and time conversion
-specifications. Time conversion specifications are two- and
-three-character sequences beginning with `<<%>>' (use `<<%%>>' to
-include a percent sign in the output). Each defined conversion
-specification selects only the specified field(s) of calendar time
-data from <<*<[timp]>>>, and converts it to a string in one of the
-following ways:
-
-o+
-o %a
-A three-letter abbreviation for the day of the week. [tm_wday]
-
-o %A
-The full name for the day of the week, one of `<<Sunday>>',
-`<<Monday>>', `<<Tuesday>>', `<<Wednesday>>', `<<Thursday>>',
-`<<Friday>>', or `<<Saturday>>'. [tm_wday]
-
-o %b
-A three-letter abbreviation for the month name. [tm_mon]
-
-o %B
-The full name of the month, one of `<<January>>', `<<February>>',
-`<<March>>', `<<April>>', `<<May>>', `<<June>>', `<<July>>',
-`<<August>>', `<<September>>', `<<October>>', `<<November>>',
-`<<December>>'. [tm_mon]
-
-o %c
-A string representing the complete date and time, in the form
-`<<"%a %b %e %H:%M:%S %Y">>' (example "Mon Apr 01 13:13:13
-1992"). [tm_sec, tm_min, tm_hour, tm_mday, tm_mon, tm_year, tm_wday]
-
-o %C
-The century, that is, the year divided by 100 then truncated. For
-4-digit years, the result is zero-padded and exactly two characters;
-but for other years, there may a negative sign or more digits. In
-this way, `<<%C%y>>' is equivalent to `<<%Y>>'. [tm_year]
-
-o %d
-The day of the month, formatted with two digits (from `<<01>>' to
-`<<31>>'). [tm_mday]
-
-o %D
-A string representing the date, in the form `<<"%m/%d/%y">>'.
-[tm_mday, tm_mon, tm_year]
-
-o %e
-The day of the month, formatted with leading space if single digit
-(from `<<1>>' to `<<31>>'). [tm_mday]
-
-o %E<<x>>
-In some locales, the E modifier selects alternative representations of
-certain modifiers <<x>>. But in the "C" locale supported by newlib,
-it is ignored, and treated as %<<x>>.
-
-o %F
-A string representing the ISO 8601:2000 date format, in the form
-`<<"%Y-%m-%d">>'. [tm_mday, tm_mon, tm_year]
-
-o %g
-The last two digits of the week-based year, see specifier %G (from
-`<<00>>' to `<<99>>'). [tm_year, tm_wday, tm_yday]
-
-o %G
-The week-based year. In the ISO 8601:2000 calendar, week 1 of the year
-includes January 4th, and begin on Mondays. Therefore, if January 1st,
-2nd, or 3rd falls on a Sunday, that day and earlier belong to the last
-week of the previous year; and if December 29th, 30th, or 31st falls
-on Monday, that day and later belong to week 1 of the next year. For
-consistency with %Y, it always has at least four characters.
-Example: "%G" for Saturday 2nd January 1999 gives "1998", and for
-Tuesday 30th December 1997 gives "1998". [tm_year, tm_wday, tm_yday]
-
-o %h
-A three-letter abbreviation for the month name (synonym for
-"%b"). [tm_mon]
-
-o %H
-The hour (on a 24-hour clock), formatted with two digits (from
-`<<00>>' to `<<23>>'). [tm_hour]
-
-o %I
-The hour (on a 12-hour clock), formatted with two digits (from
-`<<01>>' to `<<12>>'). [tm_hour]
-
-o %j
-The count of days in the year, formatted with three digits
-(from `<<001>>' to `<<366>>'). [tm_yday]
-
-o %k
-The hour (on a 24-hour clock), formatted with leading space if single
-digit (from `<<0>>' to `<<23>>'). Non-POSIX extension. [tm_hour]
-
-o %l
-The hour (on a 12-hour clock), formatted with leading space if single
-digit (from `<<1>>' to `<<12>>'). Non-POSIX extension. [tm_hour]
-
-o %m
-The month number, formatted with two digits (from `<<01>>' to `<<12>>').
-[tm_mon]
-
-o %M
-The minute, formatted with two digits (from `<<00>>' to `<<59>>'). [tm_min]
-
-o %n
-A newline character (`<<\n>>').
-
-o %O<<x>>
-In some locales, the O modifier selects alternative digit characters
-for certain modifiers <<x>>. But in the "C" locale supported by newlib, it
-is ignored, and treated as %<<x>>.
-
-o %p
-Either `<<AM>>' or `<<PM>>' as appropriate. [tm_hour]
-
-o %r
-The 12-hour time, to the second. Equivalent to "%I:%M:%S %p". [tm_sec,
-tm_min, tm_hour]
-
-o %R
-The 24-hour time, to the minute. Equivalent to "%H:%M". [tm_min, tm_hour]
-
-o %S
-The second, formatted with two digits (from `<<00>>' to `<<60>>'). The
-value 60 accounts for the occasional leap second. [tm_sec]
-
-o %t
-A tab character (`<<\t>>').
-
-o %T
-The 24-hour time, to the second. Equivalent to "%H:%M:%S". [tm_sec,
-tm_min, tm_hour]
-
-o %u
-The weekday as a number, 1-based from Monday (from `<<1>>' to
-`<<7>>'). [tm_wday]
-
-o %U
-The week number, where weeks start on Sunday, week 1 contains the first
-Sunday in a year, and earlier days are in week 0. Formatted with two
-digits (from `<<00>>' to `<<53>>'). See also <<%W>>. [tm_wday, tm_yday]
-
-o %V
-The week number, where weeks start on Monday, week 1 contains January 4th,
-and earlier days are in the previous year. Formatted with two digits
-(from `<<01>>' to `<<53>>'). See also <<%G>>. [tm_year, tm_wday, tm_yday]
-
-o %w
-The weekday as a number, 0-based from Sunday (from `<<0>>' to `<<6>>').
-[tm_wday]
-
-o %W
-The week number, where weeks start on Monday, week 1 contains the first
-Monday in a year, and earlier days are in week 0. Formatted with two
-digits (from `<<00>>' to `<<53>>'). [tm_wday, tm_yday]
-
-o %x
-A string representing the complete date, equivalent to "%m/%d/%y".
-[tm_mon, tm_mday, tm_year]
-
-o %X
-A string representing the full time of day (hours, minutes, and
-seconds), equivalent to "%H:%M:%S". [tm_sec, tm_min, tm_hour]
-
-o %y
-The last two digits of the year (from `<<00>>' to `<<99>>'). [tm_year]
-
-o %Y
-The full year, equivalent to <<%C%y>>. It will always have at least four
-characters, but may have more. The year is accurate even when tm_year
-added to the offset of 1900 overflows an int. [tm_year]
-
-o %z
-The offset from UTC. The format consists of a sign (negative is west of
-Greewich), two characters for hour, then two characters for minutes
-(-hhmm or +hhmm). If tm_isdst is negative, the offset is unknown and no
-output is generated; if it is zero, the offset is the standard offset for
-the current time zone; and if it is positive, the offset is the daylight
-savings offset for the current timezone. The offset is determined from
-the TZ environment variable, as if by calling tzset(). [tm_isdst]
-
-o %Z
-The time zone name. If tm_isdst is negative, no output is generated.
-Otherwise, the time zone name is based on the TZ environment variable,
-as if by calling tzset(). [tm_isdst]
-
-o %%
-A single character, `<<%>>'.
-o-
-
-RETURNS
-When the formatted time takes up no more than <[maxsize]> characters,
-the result is the length of the formatted string. Otherwise, if the
-formatting operation was abandoned due to lack of room, the result is
-<<0>>, and the string starting at <[s]> corresponds to just those
-parts of <<*<[format]>>> that could be completely filled in within the
-<[maxsize]> limit.
-
-PORTABILITY
-ANSI C requires <<strftime>>, but does not specify the contents of
-<<*<[s]>>> when the formatted string would require more than
-<[maxsize]> characters. Unrecognized specifiers and fields of
-<<timp>> that are out of range cause undefined results. Since some
-formats expand to 0 bytes, it is wise to set <<*<[s]>>> to a nonzero
-value beforehand to distinguish between failure and an empty string.
-This implementation does not support <<s>> being NULL, nor overlapping
-<<s>> and <<format>>.
-
-<<strftime>> requires no supporting OS subroutines.
