@class wxDateTime
- @wxheader{datetime.h}
wxDateTime class represents an absolute moment in the time.
used to contain the number of years, hours, minutes, seconds and
milliseconds.
-
- @section datetime_constants Constants
-
- Global constant wxDefaultDateTime and synonym for it wxInvalidDateTime are
+ Global constant ::wxDefaultDateTime and synonym for it ::wxInvalidDateTime are
defined. This constant will be different from any valid wxDateTime object.
- All the following constants are defined inside wxDateTime class (i.e., to
- refer to them you should prepend their names with "wxDateTime::").
-
- Time zone symbolic names:
-
- @code
- enum TZ
- {
- // the time in the current time zone
- Local,
-
- // zones from GMT (= Greenwhich Mean Time): they're guaranteed to be
- // consequent numbers, so writing something like `GMT0 + offset' is
- // safe if abs(offset) <= 12
-
- // underscore stands for minus
- GMT_12, GMT_11, GMT_10, GMT_9, GMT_8, GMT_7,
- GMT_6, GMT_5, GMT_4, GMT_3, GMT_2, GMT_1,
- GMT0,
- GMT1, GMT2, GMT3, GMT4, GMT5, GMT6,
- GMT7, GMT8, GMT9, GMT10, GMT11, GMT12, GMT13,
- // Note that GMT12 and GMT_12 are not the same: there is a difference
- // of exactly one day between them
-
- // some symbolic names for TZ
-
- // Europe
- WET = GMT0, // Western Europe Time
- WEST = GMT1, // Western Europe Summer Time
- CET = GMT1, // Central Europe Time
- CEST = GMT2, // Central Europe Summer Time

- };
- @endcode
-
- Month names: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec and
- Inv_Month for an invalid month are the values of @c wxDateTime::Month enum.
-
- Likewise, Sun, Mon, Tue, Wed, Thu, Fri, Sat, and Inv_WeekDay are the values
- in @c wxDateTime::WeekDay enum.
-
- Finally, Inv_Year is defined to be an invalid value for year parameter.
-
- GetMonthName() and GetWeekDayName() functions use the following flags:
-
- @code
- enum NameFlags
- {
- Name_Full = 0x01, // return full name
- Name_Abbr = 0x02 // return abbreviated name
- };
- @endcode
-
- Several functions accept an extra parameter specifying the calendar to use
- (although most of them only support now the Gregorian calendar). This
- parameters is one of the following values:
-
- @code
- enum Calendar
- {
- Gregorian, // calendar currently in use in Western countries
- Julian // calendar in use since -45 until the 1582 (or later)
- };
- @endcode
-
- Date calculations often depend on the country and wxDateTime allows to set
- the country whose conventions should be used using SetCountry(). It takes
- one of the following values as parameter:
-
- @code
- enum Country
- {
- Country_Unknown, // no special information for this country
- Country_Default, // set the default country with SetCountry() method
- // or use the default country with any other
-
- Country_WesternEurope_Start,
- Country_EEC = Country_WesternEurope_Start,
- France,
- Germany,
- UK,
- Country_WesternEurope_End = UK,
-
- Russia,
-
- USA
- };
- @endcode
-
- Different parts of the world use different conventions for the week start.
- In some countries, the week starts on Sunday, while in others -- on Monday.
- The ISO standard doesn't address this issue, so we support both conventions
- in the functions whose result depends on it (GetWeekOfYear() and
- GetWeekOfMonth()).
-
- The desired behvaiour may be specified by giving one of the following
- constants as argument to these functions:
-
- @code
- enum WeekFlags
- {
- Default_First, // Sunday_First for US, Monday_First for the rest
- Monday_First, // week starts with a Monday
- Sunday_First // week starts with a Sunday
- };
