GETDATE(3P) POSIX Programmer's Manual GETDATE(3P)
PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
getdate - convert user format date and time
SYNOPSIS
#include <time.h>
struct tm *getdate(const char *string);
DESCRIPTION
The getdate() function shall convert a string representation of a date or time into a broken-down time.
The external variable or macro getdate_err is used by getdate() to return error values.
Templates are used to parse and interpret the input string. The templates are contained in a text file identified by the environment vari-
able DATEMSK. The DATEMSK variable should be set to indicate the full pathname of the file that contains the templates. The first line in
the template that matches the input specification is used for interpretation and conversion into the internal time format.
The following conversion specifications shall be supported:
%% Equivalent to % .
%a Abbreviated weekday name.
%A Full weekday name.
%b Abbreviated month name.
%B Full month name.
%c Locale's appropriate date and time representation.
%C Century number [00,99]; leading zeros are permitted but not required.
%d Day of month [01,31]; the leading 0 is optional.
%D Date as %m / %d / %y .
%e Equivalent to %d .
%h Abbreviated month name.
%H Hour [00,23].
%I Hour [01,12].
%m Month number [01,12].
%M Minute [00,59].
%n Equivalent to <newline>.
%p Locale's equivalent of either AM or PM.
%r The locale's appropriate representation of time in AM and PM notation. In the POSIX locale, this shall be equivalent to %I : %M :
%S %p .
%R Time as %H : %M .
%S Seconds [00,60]. The range goes to 60 (rather than stopping at 59) to allow positive leap seconds to be expressed. Since leap sec-
onds cannot be predicted by any algorithm, leap second data must come from some external source.
%t Equivalent to <tab>.
%T Time as %H : %M : %S .
%w Weekday number (Sunday = [0,6]).
%x Locale's appropriate date representation.
%X Locale's appropriate time representation.
%y Year within century. When a century is not otherwise specified, values in the range [69,99] shall refer to years 1969 to 1999 inclu-
sive, and values in the range [00,68] shall refer to years 2000 to 2068 inclusive.
Note:
It is expected that in a future version of IEEE Std 1003.1-2001 the default century inferred from a 2-digit year will change. (This
would apply to all commands accepting a 2-digit year as input.)
%Y Year as "ccyy" (for example, 2001).
%Z Timezone name or no characters if no timezone exists. If the timezone supplied by %Z is not the timezone that getdate() expects, an
invalid input specification error shall result. The getdate() function calculates an expected timezone based on information supplied
to the function (such as the hour, day, and month).
The match between the template and input specification performed by getdate() shall be case-insensitive.
The month and weekday names can consist of any combination of upper and lowercase letters. The process can request that the input date or
time specification be in a specific language by setting the LC_TIME category (see setlocale()).
Leading zeros are not necessary for the descriptors that allow leading zeros. However, at most two digits are allowed for those descrip-
tors, including leading zeros. Extra whitespace in either the template file or in string shall be ignored.
The results are undefined if the conversion specifications %c, %x, and %X include unsupported conversion specifications.
The following rules apply for converting the input specification into the internal format:
* If %Z is being scanned, then getdate() shall initialize the broken-down time to be the current time in the scanned timezone. Otherwise,
it shall initialize the broken-down time based on the current local time as if localtime() had been called.
* If only the weekday is given, the day chosen shall be the day, starting with today and moving into the future, which first matches the
named day.
* If only the month (and no year) is given, the month chosen shall be the month, starting with the current month and moving into the
future, which first matches the named month. The first day of the month shall be assumed if no day is given.
* If no hour, minute, and second are given, the current hour, minute, and second shall be assumed.
* If no date is given, the hour chosen shall be the hour, starting with the current hour and moving into the future, which first matches
the named hour.
If a conversion specification in the DATEMSK file does not correspond to one of the conversion specifications above, the behavior is
unspecified.
The getdate() function need not be reentrant. A function that is not required to be reentrant is not required to be thread-safe.
RETURN VALUE
Upon successful completion, getdate() shall return a pointer to a struct tm. Otherwise, it shall return a null pointer and set getdate_err
to indicate the error.
ERRORS
The getdate() function shall fail in the following cases, setting getdate_err to the value shown in the list below. Any changes to errno
are unspecified.
1. The DATEMSK environment variable is null or undefined.
2. The template file cannot be opened for reading.
3. Failed to get file status information.
4. The template file is not a regular file.
5. An I/O error is encountered while reading the template file.
6. Memory allocation failed (not enough memory available).
7. There is no line in the template that matches the input.
8. Invalid input specification. For example, February 31; or a time is specified that cannot be represented in a time_t (representing the
time in seconds since the Epoch).
The following sections are informative.
EXAMPLES
1. The following example shows the possible contents of a template:
%m
%A %B %d, %Y, %H:%M:%S
%A
%B
%m/%d/%y %I %p
%d,%m,%Y %H:%M
at %A the %dst of %B in %Y
run job at %I %p,%B %dnd
%A den %d. %B %Y %H.%M Uhr
2. The following are examples of valid input specifications for the template in Example 1:
getdate("10/1/87 4 PM");
getdate("Friday");
getdate("Friday September 18, 1987, 10:30:30");
getdate("24,9,1986 10:30");
getdate("at monday the 1st of december in 1986");
getdate("run job at 3 PM, december 2nd");
If the LC_TIME category is set to a German locale that includes freitag as a weekday name and oktober as a month name, the following would
be valid:
getdate("freitag den 10. oktober 1986 10.30 Uhr");
3. The following example shows how local date and time specification can be defined in the template:
Invocation Line in Template
getdate("11/27/86") %m/%d/%y
getdate("27.11.86") %d.%m.%y
getdate("86-11-27") %y-%m-%d
getdate("Friday 12:00:00") %A %H:%M:%S
4. The following examples help to illustrate the above rules assuming that the current date is Mon Sep 22 12:19:47 EDT 1986 and the
LC_TIME category is set to the default C locale:
Input Line in Template Date
Mon %a Mon Sep 22 12:19:47 EDT 1986
Sun %a Sun Sep 28 12:19:47 EDT 1986
Fri %a Fri Sep 26 12:19:47 EDT 1986
September %B Mon Sep 1 12:19:47 EDT 1986
January %B Thu Jan 1 12:19:47 EST 1987
December %B Mon Dec 1 12:19:47 EST 1986
Sep Mon %b %a Mon Sep 1 12:19:47 EDT 1986
Jan Fri %b %a Fri Jan 2 12:19:47 EST 1987
Dec Mon %b %a Mon Dec 1 12:19:47 EST 1986
Jan Wed 1989 %b %a %Y Wed Jan 4 12:19:47 EST 1989
Fri 9 %a %H Fri Sep 26 09:00:00 EDT 1986
Feb 10:30 %b %H:%S Sun Feb 1 10:00:30 EST 1987
10:30 %H:%M Tue Sep 23 10:30:00 EDT 1986
13:30 %H:%M Mon Sep 22 13:30:00 EDT 1986
APPLICATION USAGE
Although historical versions of getdate() did not require that <time.h> declare the external variable getdate_err, this volume of
IEEE Std 1003.1-2001 does require it. The standard developers encourage applications to remove declarations of getdate_err and instead
incorporate the declaration by including <time.h>.
Applications should use %Y (4-digit years) in preference to %y (2-digit years).
RATIONALE
In standard locales, the conversion specifications %c, %x, and %X do not include unsupported conversion specifiers and so the text regard-
ing results being undefined is not a problem in that case.
FUTURE DIRECTIONS
None.
