+\membersection{wxDateTime::ParseRfc822Date}\label{wxdatetimeparserfc822date}

+\func{const wxChar *}{ParseRfc822Date}{\param{const wxChar* }{date}}
+
+Parses the string {\it date} looking for a date formatted according to the RFC
+822 in it. The exact description of this format may, of course, be found in
+the RFC (section $5$), but, briefly, this is the format used in the headers of
+Internet email messages and one of the most common strings expressing date in
+this format may be something like {\tt "Sat, 18 Dec 1999 00:48:30 +0100"}.
+
+Returns {\tt NULL} if the conversion failed, otherwise return the pointer to
+the character immediately following the part of the string which could be
+parsed. If the entire string contains only the date in RFC 822 format,
+the returned pointer will be pointing to a {\tt NUL} character.
+
+This function is intentionally strict, it will return an error for any string
+which is not RFC 822 compliant. If you need to parse date formatted in more
+free ways, you should use \helpref{ParseDateTime}{wxdatetimeparsedatetime} or
+\helpref{ParseDate}{wxdatetimeparsedate} instead.

+
+\func{const wxChar *}{ParseFormat}{\param{const wxChar *}{date}, \param{const wxChar *}{format = wxDefaultDateTimeFormat}, \param{const wxDateTime\& }{dateDef = wxDefaultDateTime}}
+
+This function parses the string {\it date} according to the given
+{\it format}. The system {\tt strptime(3)} function is used whenever available,
+but even if it is not, this function is still implemented, although support
+for locale-dependent format specifiers such as {\tt "\%c"}, {\tt "\%x"} or {\tt "\%X"} may
+not be perfect and GNU extensions such as {\tt "\%z"} and {\tt "\%Z"} are
+not implemented. This function does handle the month and weekday
+names in the current locale on all platforms, however.
+
+Please see the description of the ANSI C function {\tt strftime(3)} for the syntax
+of the format string.
+
+The {\it dateDef} parameter is used to fill in the fields which could not be
+determined from the format string. For example, if the format is {\tt "\%d"} (the
+ay of the month), the month and the year are taken from {\it dateDef}. If
+it is not specified, \helpref{Today}{wxdatetimetoday} is used as the
+default date.
+
+Returns {\tt NULL} if the conversion failed, otherwise return the pointer to
+the character which stopped the scan.
+
+
+\membersection{wxDateTime::ParseDateTime}\label{wxdatetimeparsedatetime}
+
+\func{const wxChar *}{ParseDateTime}{\param{const wxChar *}{datetime}}
+
+Parses the string {\it datetime} containing the date and time in free format.
+This function tries as hard as it can to interpret the given string as date
+and time. Unlike \helpref{ParseRfc822Date}{wxdatetimeparserfc822date}, it
+will accept anything that may be accepted and will only reject strings which
+can not be parsed in any way at all.
+
+Returns {\tt NULL} if the conversion failed, otherwise return the pointer to
+the character which stopped the scan.
+
+
+\membersection{wxDateTime::ParseDate}\label{wxdatetimeparsedate}
+
+\func{const wxChar *}{ParseDate}{\param{const wxChar *}{date}}

+This function is like \helpref{ParseDateTime}{wxdatetimeparsedatetime}, but it
+only allows the date to be specified. It is thus less flexible then
+\helpref{ParseDateTime}{wxdatetimeparsedatetime}, but also has less chances to
+misinterpret the user input.
+
+Returns {\tt NULL} if the conversion failed, otherwise return the pointer to
+the character which stopped the scan.
+
+
+\membersection{wxDateTime::ParseTime}\label{wxdatetimeparsetime}
+
+\func{const wxChar *}{ParseTime}{\param{const wxChar *}{time}}
+
+This functions is like \helpref{ParseDateTime}{wxdatetimeparsedatetime}, but

+\membersection{wxDateTime::Format}\label{wxdatetimeformat}
+
+\constfunc{wxString }{Format}{\param{const wxChar *}{format = wxDefaultDateTimeFormat}, \param{const TimeZone\& }{tz = Local}}
+
+This function does the same as the standard ANSI C {\tt strftime(3)} function.
+Please see its description for the meaning of {\it format} parameter.
+
+It also accepts a few wxWidgets-specific extensions: you can optionally specify
+the width of the field to follow using {\tt printf(3)}-like syntax and the
+format specification {\tt \%l} can be used to get the number of milliseconds.

+\constfunc{wxDateTime}{GetWeekDay}{\param{WeekDay }{weekday}, \param{int }{n = 1}, \param{Month }{month = Inv\_Month}, \param{int }{year = Inv\_Year}}

+
+\func{bool}{SetToLastWeekDay}{\param{WeekDay }{weekday}, \param{Month }{month = Inv\_Month}, \param{int }{year = Inv\_Year}}
+
+The effect of calling this function is the same as of calling
+{\tt SetToWeekDay(-1, weekday, month, year)}. The date will be set to the last
+{\it weekday} in the given month and year (the current ones by default).
+
+Always returns {\tt true}.

+\func{wxDateTime}{GetLastWeekDay}{\param{WeekDay }{weekday}, \param{Month }{month = Inv\_Month}, \param{int }{year = Inv\_Year}}

+
+\func{static wxDateTime}{SetToWeekOfYear}{\param{int }{year}, \param{wxDateTime\_t }{numWeek}, \param{WeekDay }{weekday = Mon}}
+
+Set the date to the given \arg{weekday} in the week number \arg{numWeek} of the
+given \arg{year} . The number should be in range $1\ldots53$.
+
+Note that the returned date may be in a different year than the one passed to
+this function because both the week $1$ and week $52$ or $53$ (for leap years)
+contain days from different years. See
+\helpref{GetWeekOfYear}{wxdatetimegetweekofyear} for the explanation of how the
+year weeks are counted.
+

+\membersection{wxDateTime::SetToLastMonthDay}\label{wxdatetimesettolastmonthday}
+
+\func{wxDateTime\&}{SetToLastMonthDay}{\param{Month }{month = Inv\_Month}, \param{int }{year = Inv\_Year}}
+
+Sets the date to the last day in the specified month (the current one by
+default).
+
+Returns the reference to the modified object itself.
+
+
+\membersection{wxDateTime::GetLastMonthDay}\label{wxdatetimegetlastmonthday}
+
+\constfunc{wxDateTime}{GetLastMonthDay}{\param{Month }{month = Inv\_Month}, \param{int }{year = Inv\_Year}}
+
+Returns the copy of this object to which
+\helpref{SetToLastMonthDay}{wxdatetimesettolastmonthday} was applied.
+
+
+\membersection{wxDateTime::SetToYearDay}\label{wxdatetimesettoyearday}
+
+\func{wxDateTime\&}{SetToYearDay}{\param{wxDateTime\_t }{yday}}
+
+Sets the date to the day number {\it yday} in the same year (i.e., unlike the
+other functions, this one does not use the current year). The day number
+should be in the range $1\ldots366$ for the leap years and $1\ldots365$ for
+the other ones.
+
+Returns the reference to the modified object itself.
+
+
+\membersection{wxDateTime::GetYearDay}\label{wxdatetimegetyearday}
+
+\constfunc{wxDateTime}{GetYearDay}{\param{wxDateTime\_t }{yday}}
+
+Returns the copy of this object to which
+\helpref{SetToYearDay}{wxdatetimesettoyearday} was applied.

+\membersection{wxDateTime::GetModifiedJulianDayNumber}\label{wxdatetimegetmodifiedjuliandaynumber}
+
+\constfunc{double}{GetModifiedJulianDayNumber}{\void}
+
+Returns the {\it Modified Julian Day Number} (MJD) which is, by definition,
+equal to $JDN - 2400000.5$. The MJDs are simpler to work with as the integral
+MJDs correspond to midnights of the dates in the Gregorian calendar and not th
+noons like JDN. The MJD $0$ is Nov 17, 1858.

+
+\membersection{wxDateTime::GetMJD}\label{wxdatetimegetmjd}

+\membersection{wxDateTime::GetRataDie}\label{wxdatetimegetratadie}
+
+\constfunc{double}{GetRataDie}{\void}
+
+Return the {\it Rata Die number} of this date.
+
+By definition, the Rata Die number is a date specified as the number of days
+relative to a base date of December 31 of the year 0. Thus January 1 of the
+year 1 is Rata Die day 1.
