## Detailed Description

A relative measure of time.

The time is stored as a number of seconds, at double-precision floating point accuracy, and may be positive or negative.

If you need an absolute time, (i.e. a date + time), see the Time class.

## Constructor & Destructor Documentation

## ◆ RelativeTime() [1/2]

RelativeTime::RelativeTime | ( | double | seconds = 0.0 | ) |
| explicit noexcept

Creates a RelativeTime.

Parameters

  seconds | the number of seconds, which may be +ve or -ve.

See also
  milliseconds, minutes, hours, days, weeks

## ◆ RelativeTime() [2/2]

RelativeTime::RelativeTime | ( | const RelativeTime & | other | ) |
| noexcept

Copies another relative time.

## ◆ ~RelativeTime()

RelativeTime::~RelativeTime | ( |  | ) |
| noexcept

Destructor.

## Member Function Documentation

## ◆ operator=()

RelativeTime & RelativeTime::operator= | ( | const RelativeTime & | other | ) |
| noexcept

Copies another relative time.

## ◆ milliseconds() [1/2]

static RelativeTime RelativeTime::milliseconds | ( | int | milliseconds | ) |
| static noexcept

Creates a new RelativeTime object representing a number of milliseconds.

See also
  seconds, minutes, hours, days, weeks

## ◆ milliseconds() [2/2]

static RelativeTime RelativeTime::milliseconds | ( | int64 | milliseconds | ) |
| static noexcept

Creates a new RelativeTime object representing a number of milliseconds.

See also
  seconds, minutes, hours, days, weeks

## ◆ seconds()

static RelativeTime RelativeTime::seconds | ( | double | seconds | ) |
| static noexcept

Creates a new RelativeTime object representing a number of seconds.

See also
  milliseconds, minutes, hours, days, weeks

## ◆ minutes()

static RelativeTime RelativeTime::minutes | ( | double | numberOfMinutes | ) |
| static noexcept

Creates a new RelativeTime object representing a number of minutes.

See also
  milliseconds, hours, days, weeks

## ◆ hours()

static RelativeTime RelativeTime::hours | ( | double | numberOfHours | ) |
| static noexcept

Creates a new RelativeTime object representing a number of hours.

See also
  milliseconds, minutes, days, weeks

## ◆ days()

static RelativeTime RelativeTime::days | ( | double | numberOfDays | ) |
| static noexcept

Creates a new RelativeTime object representing a number of days.

See also
  milliseconds, minutes, hours, weeks

## ◆ weeks()

static RelativeTime RelativeTime::weeks | ( | double | numberOfWeeks | ) |
| static noexcept

Creates a new RelativeTime object representing a number of weeks.

See also
  milliseconds, minutes, hours, days

## ◆ inMilliseconds()

int64 RelativeTime::inMilliseconds | ( |  | ) | const
| noexcept

Returns the number of milliseconds this time represents.

See also
  milliseconds, inSeconds, inMinutes, inHours, inDays, inWeeks

## ◆ inSeconds()

double RelativeTime::inSeconds | ( |  | ) | const
| noexcept

Returns the number of seconds this time represents.

See also
  inMilliseconds, inMinutes, inHours, inDays, inWeeks

## ◆ inMinutes()

double RelativeTime::inMinutes | ( |  | ) | const
| noexcept

Returns the number of minutes this time represents.

See also
  inMilliseconds, inSeconds, inHours, inDays, inWeeks

## ◆ inHours()

double RelativeTime::inHours | ( |  | ) | const
| noexcept

Returns the number of hours this time represents.

See also
  inMilliseconds, inSeconds, inMinutes, inDays, inWeeks

## ◆ inDays()

double RelativeTime::inDays | ( |  | ) | const
| noexcept

Returns the number of days this time represents.

See also
  inMilliseconds, inSeconds, inMinutes, inHours, inWeeks

## ◆ inWeeks()

double RelativeTime::inWeeks | ( |  | ) | const
| noexcept

Returns the number of weeks this time represents.

See also
  inMilliseconds, inSeconds, inMinutes, inHours, inDays

## ◆ getDescription()

String RelativeTime::getDescription | ( | const String & | returnValueForZeroTime = "0" | ) | const

Returns a readable textual description of the time.

The exact format of the string returned will depend on the magnitude of the time - e.g.

"1 min 4 secs", "1 hr 45 mins", "2 weeks 5 days", "140 ms"

so that only the two most significant units are printed.

The returnValueForZeroTime value is the result that is returned if the length is zero. Depending on your application you might want to use this to return something more relevant like "empty" or "0 secs", etc.

  inMilliseconds, inSeconds, inMinutes, inHours, inDays, inWeeks

## ◆ getApproximateDescription()

String RelativeTime::getApproximateDescription | ( |  | ) | const

This returns a string that roughly describes how long ago this time was, which can be handy for showing ages of files, etc.

This will only attempt to be accurate to within the nearest order of magnitude so returns strings such as "5 years", "2 weeks", "< 1 minute", "< 1 sec" etc.

## ◆ operator+=() [1/2]

RelativeTime RelativeTime::operator+= | ( | RelativeTime | timeToAdd | ) |
| noexcept

Adds another RelativeTime to this one.

## ◆ operator-=() [1/2]

RelativeTime RelativeTime::operator-= | ( | RelativeTime | timeToSubtract | ) |
| noexcept

Subtracts another RelativeTime from this one.

## ◆ operator+=() [2/2]

RelativeTime RelativeTime::operator+= | ( | double | secondsToAdd | ) |
| noexcept

Adds a number of seconds to this time.

## ◆ operator-=() [2/2]

RelativeTime RelativeTime::operator-= | ( | double | secondsToSubtract | ) |
| noexcept

Subtracts a number of seconds from this time.
