+\membersection{wxTimeSpan::Abs}\label{wxtimespanabs}
+
+\constfunc{wxTimeSpan}{Abs}{\void}
+
+Returns the absolute value of the timespan: does not modify the
+object.
+
+
+\membersection{wxTimeSpan::Add}\label{wxtimespanadd}
+
+\constfunc{wxTimeSpan}{Add}{\param{const wxTimeSpan\& }{diff}}
+
+\func{wxTimeSpan\&}{Add}{\param{const wxTimeSpan\& }{diff}}
+
+\func{wxTimeSpan\&}{operator$+=$}{\param{const wxTimeSpan\&}{diff}}
+
+Returns the sum of two timespans.
+
+
+\membersection{wxTimeSpan::Days}\label{wxtimespandays}
+
+\func{static wxTimespan}{Days}{\param{long }{days}}
+
+Returns the timespan for the given number of days.
+
+
+\membersection{wxTimeSpan::Day}\label{wxtimespanday}
+
+\func{static wxTimespan}{Day}{\void}
+
+Returns the timespan for one day.
+
+
+\membersection{wxTimeSpan::Format}\label{wxtimespanformat}
+
+\func{wxString}{Format}{\param{const wxChar * }{format = wxDefaultTimeSpanFormat}}
+
+Returns the string containing the formatted representation of the time span.
+The following format specifiers are allowed after \%:
+
+\twocolwidtha{5cm}%
+\begin{twocollist}\itemsep=0pt
+\twocolitem{H}{number of {\bf H}ours}
+\twocolitem{M}{number of {\bf M}inutes}
+\twocolitem{S}{number of {\bf S}econds}
+\twocolitem{l}{number of mi{\bf l}liseconds}
+\twocolitem{D}{number of {\bf D}ays}
+\twocolitem{E}{number of w{\bf E}eks}
+\twocolitem{\%}{the percent character}
+\end{twocollist}
+
+Note that, for example, the number of hours in the description above is not
+well defined: it can be either the total number of hours (for example, for a
+time span of $50$ hours this would be $50$) or just the hour part of the time
+span, which would be $2$ in this case as $50$ hours is equal to $2$ days and
+$2$ hours.
+
+wxTimeSpan resolves this ambiguity in the following way: if there had been,
+indeed, the {\tt \%D} format specified preceding the {\tt \%H}, then it is
+interpreted as $2$. Otherwise, it is $50$.
+
+The same applies to all other format specifiers: if they follow a specifier of
+larger unit, only the rest part is taken, otherwise the full value is used.
