[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. -*/ - -#include <stddef.h> -#include <stdio.h> -#include <time.h> -#include <string.h> -#include <stdlib.h> -#include "local.h" - -static _CONST int dname_len[7] = -{6, 6, 7, 9, 8, 6, 8}; - -static _CONST char *_CONST dname[7] = -{"Sunday", "Monday", "Tuesday", "Wednesday", - "Thursday", "Friday", "Saturday"}; - -static _CONST int mname_len[12] = -{7, 8, 5, 5, 3, 4, 4, 6, 9, 7, 8, 8}; - -static _CONST char *_CONST mname[12] = -{"January", "February", "March", "April", - "May", "June", "July", "August", "September", "October", "November", - "December"}; - -/* Using the tm_year, tm_wday, and tm_yday components of TIM_P, return - -1, 0, or 1 as the adjustment to add to the year for the ISO week - numbering used in "%g%G%V", avoiding overflow. */ -static int -_DEFUN (iso_year_adjust, (tim_p), - _CONST struct tm *tim_p) -{ - /* Account for fact that tm_year==0 is year 1900. */ - int leap = isleap (tim_p->tm_year + (YEAR_BASE - - (tim_p->tm_year < 0 ? 0 : 2000))); - - /* Pack the yday, wday, and leap year into a single int since there are so - many disparate cases. */ -#define PACK(yd, wd, lp) (((yd) << 4) + (wd << 1) + (lp)) - switch (PACK (tim_p->tm_yday, tim_p->tm_wday, leap)) - { - case PACK (0, 5, 0): /* Jan 1 is Fri, not leap. */ - case PACK (0, 6, 0): /* Jan 1 is Sat, not leap. */ - case PACK (0, 0, 0): /* Jan 1 is Sun, not leap. */ - case PACK (0, 5, 1): /* Jan 1 is Fri, leap year. */ - case PACK (0, 6, 1): /* Jan 1 is Sat, leap year. */ - case PACK (0, 0, 1): /* Jan 1 is Sun, leap year. */ - case PACK (1, 6, 0): /* Jan 2 is Sat, not leap. */ - case PACK (1, 0, 0): /* Jan 2 is Sun, not leap. */ - case PACK (1, 6, 1): /* Jan 2 is Sat, leap year. */ - case PACK (1, 0, 1): /* Jan 2 is Sun, leap year. */ - case PACK (2, 0, 0): /* Jan 3 is Sun, not leap. */ - case PACK (2, 0, 1): /* Jan 3 is Sun, leap year. */ - return -1; /* Belongs to last week of previous year. */ - case PACK (362, 1, 0): /* Dec 29 is Mon, not leap. */ - case PACK (363, 1, 1): /* Dec 29 is Mon, leap year. */ - case PACK (363, 1, 0): /* Dec 30 is Mon, not leap. */ - case PACK (363, 2, 0): /* Dec 30 is Tue, not leap. */ - case PACK (364, 1, 1): /* Dec 30 is Mon, leap year. */ - case PACK (364, 2, 1): /* Dec 30 is Tue, leap year. */ - case PACK (364, 1, 0): /* Dec 31 is Mon, not leap. */ - case PACK (364, 2, 0): /* Dec 31 is Tue, not leap. */ - case PACK (364, 3, 0): /* Dec 31 is Wed, not leap. */ - case PACK (365, 1, 1): /* Dec 31 is Mon, leap year. */ - case PACK (365, 2, 1): /* Dec 31 is Tue, leap year. */ - case PACK (365, 3, 1): /* Dec 31 is Wed, leap year. */ - return 1; /* Belongs to first week of next year. */ - } - return 0; /* Belongs to specified year. */ -#undef PACK -} - -size_t -_DEFUN (strftime, (s, maxsize, format, tim_p), - char *s _AND - size_t maxsize _AND - _CONST char *format _AND - _CONST struct tm *tim_p) -{ - size_t count = 0; - int i; - - for (;;) - { - while (*format && *format != '%') - { - if (count < maxsize - 1) - s[count++] = *format++; - else - return 0; - } - - if (*format == '\0') - break; - - format++; - if (*format == 'E' || *format == 'O') - format++; - - switch (*format) - { - case 'a': - for (i = 0; i < 3; i++) - { - if (count < maxsize - 1) - s[count++] = - dname[tim_p->tm_wday][i]; - else - return 0; - } - break; - case 'A': - for (i = 0; i < dname_len[tim_p->tm_wday]; i++) - { - if (count < maxsize - 1) - s[count++] = - dname[tim_p->tm_wday][i]; - else - return 0; - } - break; - case 'b': - case 'h': - for (i = 0; i < 3; i++) - { - if (count < maxsize - 1) - s[count++] = - mname[tim_p->tm_mon][i]; - else - return 0; - } - break; - case 'B': - for (i = 0; i < mname_len[tim_p->tm_mon]; i++) - { - if (count < maxsize - 1) - s[count++] = - mname[tim_p->tm_mon][i]; - else - return 0; - } - break; - case 'c': - { - /* Length is not known because of %C%y, so recurse. */ - size_t adjust = strftime (&s[count], maxsize - count, - "%a %b %e %H:%M:%S %C%y", tim_p); - if (adjust > 0) - count += adjust; - else - return 0; - } - break; - case 'C': - { - /* Examples of (tm_year + YEAR_BASE) that show how %Y == %C%y - with 32-bit int. - %Y %C %y - 2147485547 21474855 47 - 10000 100 00 - 9999 99 99 - 0999 09 99 - 0099 00 99 - 0001 00 01 - 0000 00 00 - -001 -0 01 - -099 -0 99 - -999 -9 99 - -1000 -10 00 - -10000 -100 00 - -2147481748 -21474817 48 - - Be careful of both overflow and sign adjustment due to the - asymmetric range of years. - */ - int neg = tim_p->tm_year < -YEAR_BASE; - int century = tim_p->tm_year >= 0 - ? tim_p->tm_year / 100 + YEAR_BASE / 100 - : abs (tim_p->tm_year + YEAR_BASE) / 100; - count += snprintf (&s[count], maxsize - count, "%s%.*d", - neg ?
