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

inMilliseconds()

int64 RelativeTime::inMilliseconds ( ) const

noexcept

Returns the number of milliseconds this time represents.

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.

inWeeks()

double RelativeTime::inWeeks ( ) const

noexcept

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.

See also

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.
