Tempo was designed to work both in OSX and in iOS (7.0+). Work with the time or dates can be cumbersome, iOS development. Tempo allows you to deal easly with date and time. Basics manipulations are already implemented in Tempo.

How to use it ?

You can build a new Tempo, with severals way:

varbirthdayTempo=Tempo{(newTemp)->()in
newTemp.years =2014
newTemp.months =12
newTemp.days =12}varcurrentTime=Tempo()vartempoWithDate=Tempo(date: customNSDate)vartempoWithString=Tempo(stringDate:"12/02/1992")vartempoCustomFormat=Tempo(stringDate:"12/02/1992","dd/MM/yyyy")

Convert Tempo to string, with specific format: All the basics format work with Tempo.

Tempo().format() // "2014 12 12 00:00:00"
Tempo().format("yyyy MM dd") // "2014 12 12"
Tempo().format("dd EE / MMMM / yyyy") // "12 Fri / December / 2014"
lett1=Tempo(stringDate:"2014 12 12")
//change the locale date
t1.locale =NSLocale(localeIdentifier:"fr_FR")
t1.format(format:"EEEE") // "mercredi"
t1.locale =NSLocale(localeIdentifier:"en_EN")
t1.format(format:"EEEE") // "Wednesday"
t1.locale =NSLocale(localeIdentifier:"es_ES")
t1.format(format:"EEEE") // "miércoles"

With Tempo you have access to the date components and the date itself: The date components and the date are linked.

lett=Tempo()
t.years! +=1
t.days! +=20
t.date =NSDate()

You can also make simple comparaison between two Tempo or with NSDate:

varnewDate=Tempo{(newTemp)->()in
newTemp.years =2014
newTemp.months =10
newTemp.days =12
newTemp.minutes =2}println("newDate: \(newDate.formatDate())") // "2014 10 12 00:02:00"
println("current time : \(Tempo().formatDate())") // "2014 12 18 15:40:11"
Tempo().isAfter(newDate) // "True"
Tempo().isBefore(newDate) // "False"
Tempo().isSame(newDate) // "False"
Tempo().isBetween(tempoLeft:newDate, tempoRight:d2) // "True"
Tempo().isToday(newDate) // "False"
Tempo().isThisMonth(newDate) // "true"
Tempo().isThisYear(newDate) // "true"

Tempo also override operator the simple comparaison :

// same as tempo1.isBefore(tempo2)
if tempo1 < tempo2 {}
// same as tempo1.isAfter(tempo2)
if tempo1 > tempo2 {}
// same as tempo1.isSame(tempo2)
if tempo1 == tempo2 {}
// You can add two tempo together:
letresult:Tempo= tempo1 + tempo2
letresult:Tempo= tempo1 - tempo2

Know difference between two date component:

varnewDate=Tempo{(newTemp)->()in
newTemp.years =2014
newTemp.months =10
newTemp.days =12
newTemp.minutes =2}Tempo().diffYear(newDate) // "0"
Tempo().diffMonth(newDate) // "-4"
Tempo().diffWeek(newDate) // "-18"
Tempo().diffDay(newDate) // "-130"

Get time ago from date or current time: Return literal string with the difference between two Tempo. Can be usefull in for display in message or feeds. You have three diferent kind of display.

vardate=Tempo{(newTemp)->()in
newTemp.years =2014
newTemp.months =10
newTemp.days =25}
// Classic display
date.timeAgoNow() // "3 months ago"
date.timeAgo(Tempo())
// Short display
date.timeAgoSimpleNow() // "3mo"
date.timeAgoSimple(Tempo())
// More readable display
date.dateTimeUntilNow() // "This year"
date.dateTimeUntil(Tempo())
