## Constructor & Destructor Documentation

## ◆ wxTimeSpan() [1/2]

wxTimeSpan::wxTimeSpan | ( |  | ) |

Default constructor, constructs a zero timespan.

## ◆ wxTimeSpan() [2/2]

wxTimeSpan::wxTimeSpan | ( | long | hours,
|  | long | min = `0`,
|  | wxLongLong | sec = `0`,
|  | wxLongLong | msec = `0`
| ) |  |

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.

## Member Function Documentation

## ◆ Abs()

wxTimeSpan wxTimeSpan::Abs | ( |  | ) | const

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

## ◆ Add() [1/2]

wxTimeSpan wxTimeSpan::Add | ( | const wxTimeSpan & | diff | ) | const

Returns the sum of two time spans.

Returns
  A new wxDateSpan object with the result.

## ◆ Add() [2/2]

wxTimeSpan& wxTimeSpan::Add | ( | const wxTimeSpan & | diff | ) |

Adds the given wxTimeSpan to this wxTimeSpan and returns a reference to itself.

## ◆ Day()

static wxTimeSpan wxTimeSpan::Day | ( |  | ) |
| static

Returns the timespan for one day.

## ◆ Days()

static wxTimeSpan wxTimeSpan::Days | ( | long | days | ) |
| static

Returns the timespan for the given number of days.

## ◆ Format()

wxString wxTimeSpan::Format | ( | const wxString & | format = `wxDefaultTimeSpanFormat` | ) | const

Returns the string containing the formatted representation of the time span.

The following format specifiers are allowed after %:

- `H` - Number of Hours
- `M` - Number of Minutes
- `S` - Number of Seconds
- `l` - Number of Milliseconds
- `D` - Number of Days
- `E` - Number of Weeks
- `%` - The percent character

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.

## ◆ GetDays()

int wxTimeSpan::GetDays | ( |  | ) | const

Returns the difference in number of days.

## ◆ GetHours()

int wxTimeSpan::GetHours | ( |  | ) | const

Returns the difference in number of hours.

## ◆ GetMilliseconds()

wxLongLong wxTimeSpan::GetMilliseconds | ( |  | ) | const

Returns the difference in number of milliseconds.

## ◆ GetMinutes()

int wxTimeSpan::GetMinutes | ( |  | ) | const

Returns the difference in number of minutes.

## ◆ GetSeconds()

wxLongLong wxTimeSpan::GetSeconds | ( |  | ) | const

Returns the difference in number of seconds.

## ◆ GetValue()

wxLongLong wxTimeSpan::GetValue | ( |  | ) | const

Returns the internal representation of timespan.

## ◆ GetWeeks()

Returns true if two timespans are equal.

## ◆ IsLongerThan()

bool wxTimeSpan::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.
