There are 3 main classes declared in {\tt <wx/datetime.h>}: except
\helpref{wxDateTime}{wxdatetime} itself which represents an absolute
moment in time, there are also two classes -
-\helpref{wxTimeSpan}{wxtimespan} and \helpref{wxDateSpan}{wxdatespan} which
+\helpref{wxTimeSpan}{wxtimespan} and \helpref{wxDateSpan}{wxdatespan} - which
represent the intervals of time.
There are also helper classes which are used together with wxDateTime:
wxTime classes. \helpref{These classes}{tdatecompatibility} are obsolete and
superseded by wxDateTime.

\helpref{wxDateTime}{wxdatetime} stores the time as a signed number of
milliseconds since the Epoch which is fixed, by convention, to Jan 1, 1970 -
as well and support for other calendars (Maya, Hebrew, Chinese...) is not
ruled out.

While there is only one logical way to represent an absolute moment in the
time (and hence only one wxDateTime class), there are at least two methods to

+The old classes for date/time manipulations ported from wxWidgets version 1.xx
are still included but are reimplemented in terms of wxDateTime. However, using
them is strongly discouraged because they have a few quirks/bugs and were not
`Y2K' compatible.
