@class wxDateTime
- wxDateTime class represents an absolute moment in the time.
+ wxDateTime class represents an absolute moment in time.
The type @c wxDateTime_t is typedefed as unsigned short and is
used to contain the number of years, hours, minutes, seconds and
milliseconds.
+ Global constant ::wxDefaultDateTime and synonym for it ::wxInvalidDateTime are
+ defined. This constant will be different from any valid wxDateTime object.
- @section datetime_constants Constants
- Global constant wxDefaultDateTime and synonym for it wxInvalidDateTime are
- defined. This constant will be different from any valid wxDateTime object.
+ @section datetime_static Static Functions
+
+ All static functions either set or return the static variables of
+ wxDateSpan (the country), return the current moment, year, month or number
+ of days in it, or do some general calendar-related actions.
+
+ Please note that although several function accept an extra Calendar
+ parameter, it is currently ignored as only the Gregorian calendar is
+ supported. Future versions will support other calendars.
+
+ @section datetime_formatting Date Formatting and Parsing
+
+ The date formatting and parsing functions convert wxDateTime objects to and
+ from text. The conversions to text are mostly trivial: you can either do it
+ using the default date and time representations for the current locale
+ (FormatDate() and FormatTime()), using the international standard
+ representation defined by ISO 8601 (FormatISODate(), FormatISOTime() and
+ FormatISOCombined()) or by specifying any format at all and using Format()
+ directly.
+
+ The conversions from text are more interesting, as there are much more
+ possibilities to care about. The simplest cases can be taken care of with
+ ParseFormat() which can parse any date in the given (rigid) format.
+ ParseRfc822Date() is another function for parsing dates in predefined
+ format -- the one of RFC 822 which (still...) defines the format of email
+ messages on the Internet. This format cannot be described with
+ @c strptime(3)-like format strings used by Format(), hence the need for a
+ separate function.
+
+ But the most interesting functions are ParseTime(), ParseDate() and
+ ParseDateTime(). They try to parse the date and time (or only one of them)
+ in 'free' format, i.e. allow them to be specified in any of possible ways.
+ These functions will usually be used to parse the (interactive) user input
+ which is not bound to be in any predefined format. As an example,
+ ParseDate() can parse the strings such as "tomorrow", "March first" and
+ even "next Sunday".
+
+ Finally notice that each of the parsing functions is available in several
+ overloads: if the input string is a narrow (@c char *) string, then a
+ narrow pointer is returned. If the input string is a wide string, a wide
+ char pointer is returned. Finally, if the input parameter is a wxString, a
+ narrow char pointer is also returned for backwards compatibility but there
+ is also an additional argument of wxString::const_iterator type in which,
+ if it is not @NULL, an iterator pointing to the end of the scanned string
+ part is returned.
