It can read - the current date from the system clock. It provides functions for - comparing dates and for manipulating dates, e.g. by adding a - number of days or months or years. - - A TQDate object is typically created either by giving the year, - month and day numbers explicitly, or by using the static function - tqcurrentDate(), which creates a TQDate object containing the system - clock's date. An explicit date can also be set using setYMD(). The - fromString() function returns a TQDate given a string and a date - format which is used to interpret the date within the string. - - The year(), month(), and day() functions provide access to the - year, month, and day numbers. Also, dayOfWeek() and dayOfYear() - functions are provided. The same information is provided in - textual format by the toString(), shortDayName(), longDayName(), - shortMonthName() and longMonthName() functions. - - TQDate provides a full set of operators to compare two TQDate - objects where smaller means earlier and larger means later. - - You can increment (or decrement) a date by a given number of days - using addDays(). Similarly you can use addMonths() and addYears(). - The daysTo() function returns the number of days between two - dates. - - The daysInMonth() and daysInYear() functions return how many days - there are in this date's month and year, respectively. The - leapYear() function indicates whether this date is in a leap year. - - Note that TQDate should not be used for date calculations for dates - prior to the introduction of the Gregorian calendar. This calendar - was adopted by England from the 14<sup><small>th</small></sup> - September 1752 (hence this is the earliest valid TQDate), and - subsequently by most other Western countries, until 1923. - - The end of time is reached around the year 8000, by which time we - expect TQt to be obsolete. - - \sa TQTime TQDateTime TQDateEdit TQDateTimeEdit -*/ - -/*! - \enum TQt::DateFormat - - \value TextDate (default) TQt format - \value ISODate ISO 8601 extended format (YYYY-MM-DD, or with time, - YYYY-MM-DDTHH:MM:SS) - \value LocalDate locale dependent format -*/ - - -/*! - \enum TQt::TimeSpec - - \value LocalTime Locale dependent time (Timezones and Daylight Savings Time) - \value UTC Coordinated Universal Time, replaces Greenwich Time -*/ - -/*! - \fn TQDate::TQDate() - - Constructs a null date.

It can read the - current time from the system clock and measure a span of elapsed - time. It provides functions for comparing times and for - manipulating a time by adding a number of (milli)seconds. - - TQTime uses the 24-hour clock format; it has no concept of AM/PM. - It operates in local time; it knows nothing about time zones or - daylight savings time. - - A TQTime object is typically created either by giving the number of - hours, minutes, seconds, and milliseconds explicitly, or by using - the static function currentTime(), which creates a TQTime object - that contains the system's clock time. Note that the accuracy - depends on the accuracy of the underlying operating system; not - all systems provide 1-millisecond accuracy. - - The hour(), minute(), second(), and msec() functions provide - access to the number of hours, minutes, seconds, and milliseconds - of the time.

One time is considered smaller than another if it is - earlier than the other. - - The time a given number of seconds or milliseconds later than a - given time can be found using the addSecs() or addMSecs() - functions.

It is a combination of the TQDate and TQTime classes. - It can read the current datetime from the system clock. It - provides functions for comparing datetimes and for manipulating a - datetime by adding a number of seconds, days, months or years. - - A TQDateTime object is typically created either by giving a date - and time explicitly in the constructor, or by using the static - function tqcurrentDateTime(), which returns a TQDateTime object set - to the system clock's time. The date and time can be changed with - setDate() and setTime(). A datetime can also be set using the - setTime_t() function, which takes a POSIX-standard "number of - seconds since 00:00:00 on January 1, 1970" value. The fromString() - function returns a TQDateTime given a string and a date format - which is used to interpret the date within the string. - - The date() and time() functions provide access to the date and - time parts of the datetime. The same information is provided in - textual format by the toString() function. - - TQDateTime provides a full set of operators to compare two - TQDateTime objects where smaller means earlier and larger means - later. - - You can increment (or decrement) a datetime by a given number of - seconds using addSecs() or days using addDays(). Similarly you can - use addMonths() and addYears(). The daysTo() function returns the - number of days between two datetimes, and secsTo() returns the - number of seconds between two datetimes. - - The range of a datetime object is constrained to the ranges of the - TQDate and TQTime objects which it embodies. - - \sa TQDate TQTime TQDateTimeEdit -*/ - - -/*! - \fn TQDateTime::TQDateTime() - - Constructs a null datetime (i.e. null date and null time).
