Get the current century, i.e. first two digits of the year, in given calendar
(only Gregorian is currently supported).
\membersection{wxDateTime::GetTmNow}\label{wxdatetimegettmnow}
-\func{static struct tm *}{GetTmNow}{\void}
+\func{static struct tm *}{GetTmNow}{\param{struct tm *}{tm}}

+passed to the function via {\it tm} to store the result.
-Returns the current time broken down.
+\membersection{wxDateTime::GetTmNow}
+
+\func{static struct tm *}{GetTmNow}{\void}
+Returns the current time broken down. Note that this function returns a
+pointer to a static buffer that's reused by calls to this function and
+certain C library functions (e.g. localtime). If there is any chance your
+code might be used in a multi-threaded application, you really should use
+the flavour of function \helpref{wxDateTime::GetTmNow}{wxdatetimegettmnow}
+taking a parameter.
\membersection{wxDateTime::GetWeekDayName}\label{wxdatetimegetweekdayname}
Returns {\tt true} if the object represents a valid time moment.
+\membersection{wxDateTime::GetDateOnly}\label{wxdatetimegetdateonly}
+
+\constfunc{wxDateTime}{GetDateOnly}{\void}
+
+Returns the object having the same date component as this one but time of
+00:00:00.

+\constfunc{int}{GetCentury}{\param{const TimeZone\& }{tz = Local}}

+Returns the century of this date.

equivalently, the first week which has Thursday in this year. Both of these
definitions are the same as saying that the first week of the year must contain
more than half of its days in this year. Accordingly, the week number will
-always be in $1\ldots53$ range ($52$ for non leap years).

The function depends on the \helpref{week start}{wxdatetime} convention
specified by the {\it flags} argument but its results for

Returns {\tt NULL} if the conversion failed, otherwise return the pointer to

+\constfunc{wxDateTime}{FromTimezone}{\param{const TimeZone\& }{tz}, \param{bool }{noDST = false}}
+
+Transform the date from the given time zone to the local one. If {\it noDST} is
+{\tt true}, no DST adjustments will be made.
+
+Returns the date in the local time zone.

\membersection{wxDateTime::ToTimezone}\label{wxdatetimetotimezone}
\constfunc{wxDateTime}{ToTimezone}{\param{const TimeZone\& }{tz}, \param{bool }{noDST = false}}
{\it noDST} is {\tt true}, no DST adjustments will be made.

+\func{wxDateTime\&}{MakeFromTimezone}{\param{const TimeZone\& }{tz}, \param{bool }{noDST = false}}

+\membersection{wxDateTime::ToUTC}\label{wxdatetimetoutc}
-\constfunc{wxDateTime}{ToGMT}{\param{bool }{noDST = false}}
+\constfunc{wxDateTime}{ToUTC}{\param{bool }{noDST = false}}

the argument {\tt GMT0}.
