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.

<<strftime_l>> is like <<strftime>> but creates a string in a format
as expected in locale <[locale]>. If <[locale]> is LC_GLOBAL_LOCALE or
not a valid locale object, the behaviour is undefined.

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
The abbreviated weekday name according to the current locale. [tm_wday]
o %A
The full weekday name according to the current locale.
In the default "C" locale, one of `<<Sunday>>', `<<Monday>>', `<<Tuesday>>',
`<<Wednesday>>', `<<Thursday>>', `<<Friday>>', `<<Saturday>>'. [tm_wday]
o %b
The abbreviated month name according to the current locale. [tm_mon]
o %B
The full month name according to the current locale.
In the default "C" locale, one of `<<January>>', `<<February>>',
`<<March>>', `<<April>>', `<<May>>', `<<June>>', `<<July>>',
`<<August>>', `<<September>>', `<<October>>', `<<November>>',
`<<December>>'. [tm_mon]
o %c
The preferred date and time representation for the current locale.
[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]

2017-04-11 21:13:36 +00:00
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>>. In 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.

2017-04-11 21:13:36 +00:00
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
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 (c.p. %I). [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 (c.p. %H). [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>>. In newlib, it is ignored, and treated as %<<x>>.
o %p
Either `<<AM>>' or `<<PM>>' as appropriate, or the corresponding strings for
the current locale. [tm_hour]
o %P
Same as '<<%p>>', but in lowercase. This is a GNU extension. [tm_hour]
o %r
Replaced by the time in a.m. and p.m. notation. In the "C" locale this
is equivalent to "%I:%M:%S %p". In locales which don't define a.m./p.m.
notations, the result is an empty string. [tm_sec, tm_min, tm_hour]
o %R
The 24-hour time, to the minute. Equivalent to "%H:%M". [tm_min, tm_hour]
Update gcc to 7.2.0, binutils to 2.29, newlib to 2.5.0
2017-10-07 00:16:47 +00:00
o %s
The time elapsed, in seconds, since the start of the Unix epoch at
1970-01-01 00:00:00 UTC.
re-add newlib
2017-04-11 21:13:36 +00:00
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
Replaced by the preferred date representation in the current locale.
In the "C" locale this is equivalent to "%m/%d/%y".
[tm_mon, tm_mday, tm_year]
o %X
Replaced by the preferred time representation in the current locale.
In the "C" locale this is 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]
(Implementation interpretation: always positive, even for negative years.)
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>>.

2017-10-07 00:16:47 +00:00
(NOT Cygwin:) <<strftime>> ignores the LC_TIME category of the current
locale, hard-coding the "C" locale settings.
