Formatting time spans

Format

wxTimeSpan::Abs

wxTimeSpan Abs() const

Returns the absolute value of the timespan: does not modify the object.

wxTimeSpan::Add

wxTimeSpan Add(const wxTimeSpan& diff) const

wxTimeSpan& Add(const wxTimeSpan& diff)

wxTimeSpan& operator+=(const wxTimeSpan&diff)

Returns the sum of two timespans.

wxTimeSpan::Days

static wxTimespan Days(long days)

Returns the timespan for the given number of days.

wxTimeSpan::Day

static wxTimespan Day()

Returns the timespan for one day.

wxTimeSpan::Format

wxString Format(const wxChar * format = wxDefaultTimeSpanFormat)

Returns the string containing the formatted representation of the time span. The following format specifiers are allowed after %:

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 %D format specified preceding the %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.

wxTimeSpan::GetDays

int GetDays() const

Returns the difference in number of days.

wxTimeSpan::GetHours

int GetHours() const

Returns the difference in number of hours.

wxTimeSpan::GetMilliseconds

wxLongLong GetMilliseconds() const

Returns the difference in number of milliseconds.

wxTimeSpan::GetMinutes

int GetMinutes() const

Returns the difference in number of minutes.

wxTimeSpan::GetSeconds

wxLongLong GetSeconds() const

Returns the difference in number of seconds.

wxTimeSpan::GetValue

wxLongLong GetValue() const

Returns the internal representation of timespan.

wxTimeSpan::GetWeeks

int GetWeeks() const

Returns the difference in number of weeks.

wxTimeSpan::Hours

static wxTimespan Hours(long hours)

Returns the timespan for the given number of hours.

wxTimeSpan::Hour

static wxTimespan Hour()

Returns the timespan for one hour.

wxTimeSpan::IsEqualTo

bool IsEqualTo(const wxTimeSpan& ts) const

Returns true if two timespans are equal.

wxTimeSpan::IsLongerThan

bool IsLongerThan(const wxTimeSpan& ts) const

Compares two timespans: works with the absolute values, i.e. -2 hours is longer than 1 hour. Also, it will return false if the timespans are equal in absolute value.

wxTimeSpan::IsNegative

bool IsNegative() const

Returns true if the timespan is negative.

wxTimeSpan::IsNull

bool IsNull() const

Returns true if the timespan is empty.

wxTimeSpan::IsPositive

bool IsPositive() const

Returns true if the timespan is positive.

wxTimeSpan::IsShorterThan

bool IsShorterThan(const wxTimeSpan& ts) const

Compares two timespans: works with the absolute values, i.e. 1 hour is shorter than -2 hours. Also, it will return false if the timespans are equal in absolute value.

wxTimeSpan::Minutes

static wxTimespan Minutes(long min)

Returns the timespan for the given number of minutes.

wxTimeSpan::Minute

static wxTimespan Minute()

Returns the timespan for one minute.

wxTimeSpan::Multiply

wxTimeSpan Multiply(int n) const

wxTimeSpan& Multiply(int n)

wxTimeSpan& operator*=(int n)

Multiplies timespan by a scalar.

wxTimeSpan::Negate

wxTimeSpan Negate() const

Returns timespan with inverted sign.

wxTimeSpan::Neg

wxTimeSpan& Neg()

wxTimeSpan& operator-()

Negate the value of the timespan.

wxTimeSpan::Milliseconds

static wxTimespan Milliseconds(long ms)

Returns the timespan for the given number of milliseconds.

wxTimeSpan::Millisecond

static wxTimespan Millisecond()

Returns the timespan for one millisecond.

wxTimeSpan::Seconds

static wxTimespan Seconds(long sec)

Returns the timespan for the given number of seconds.

wxTimeSpan::Second

static wxTimespan Second()

Returns the timespan for one second.

wxTimeSpan::Subtract

wxTimeSpan Subtract(const wxTimeSpan&diff) const

wxTimeSpan& Subtract(const wxTimeSpan& diff)

wxTimeSpan& operator-=(const wxTimeSpan&diff)

Returns the difference of two timespans.

wxTimeSpan::Weeks

static wxTimespan Weeks(long weeks)

Returns the timespan for the given number of weeks.

wxTimeSpan::Week

static wxTimespan Week()

Returns the timespan for one week.

wxTimeSpan::wxTimeSpan

wxTimeSpan()

Default constructor, constructs a zero timespan.

wxTimeSpan(long hours, long min, long sec, long msec)

Constructs timespan from separate values for each component, with the date set to 0. Hours are not restricted to 0..24 range, neither are minutes, seconds or milliseconds.
