Usage

import TimeLord

let firstDate = TimeLord(year: 2016, month: 01, day: 01, hour: 02, minute: 30, second: 00)
let secondDate = TimeLord(year: 2015, month: 01, day: 01, hour: 02, minute: 30, second: 00)
let nowDate = TimeLord(keyWord: .Now)

if nowDate >  firstDate {
 ...
}

let newDate = secondDate.toString()
let newDate = firstDate.toStringInFormat("yyyy-MM-dd HH:mm:ss", inTimeZone: NSTimeZone(abbreviation: "MSK"))
let newDate = secondDate.addYears(11).addMonths(9).subDays(1)

Create date

// form NSDate
let date = TimeLord(date: NSDate())
// form date components
let date = TimeLord(year: 2016, month: 01, day: 08, hour: 14, minute: 25, second: 00)
let date = TimeLord(year: 2016, month: 01, day: 08, hour: 10, minute: 25, second: 00, timeZone: NSTimeZone(abbreviation: "MSK"))
// form string
let date = TimeLord(date: "2016-01-08 13:38:00")
let date = TimeLord(date: "2016-01-08 13:38:00", inFormat: "yyyy-MM-dd HH:mm:ss")
let date = TimeLord(date: "2016-01-08 09:38:00", inFormat: "yyyy-MM-dd HH:mm:ss", timeZone: NSTimeZone(abbreviation: "MSK"))
// from time interval
let date = TimeLord(timeIntervalSince1970: 1452243489)
let date = TimeLord(timeIntervalSinceNow: 1452243489)
let date = TimeLord(timeInterval: 1452243489, sinceDate: date)
let date = TimeLord(timeIntervalSinceReferenceDate: 1452243489)
// from key word
let date = TimeLord(keyWord: .Now)
let date = TimeLord(keyWord: .Today)
let date = TimeLord(keyWord: .Tomorrow)
let date = TimeLord(keyWord: .Yesterday)

Get date components

let tmDateInDefaultFormat = TimeLord(date: "2016-01-08 13:38:00")
let year = tmDateInDefaultFormat?.year
let month = tmDateInDefaultFormat?.month

let day = tmDateInDefaultFormat?.day
let hour = tmDateInDefaultFormat?.hour

let minute = tmDateInDefaultFormat?.minute
let second = tmDateInDefaultFormat?.second

let nanosecond = tmDateInDefaultFormat?.nanosecond
let dayInMonth = tmDateInDefaultFormat?.dayInMonth

let weekday = tmDateInDefaultFormat?.weekday
let weekdaySymbol = tmDateInDefaultFormat?.weekdaySymbol

let weekdayOrdinal = tmDateInDefaultFormat?.weekdayOrdinal
let quarter = tmDateInDefaultFormat?.quarter

let weekOfMonth = tmDateInDefaultFormat?.weekOfMonth
let weekOfYear = tmDateInDefaultFormat?.weekOfYear

let yearForWeekOfYear = tmDateInDefaultFormat?.yearForWeekOfYear
let era = tmDateInDefaultFormat?.era

Get date as string

let date = TimeLord(year: 2016, month: 01, day: 08, hour: 23, minute: 00, second: 00)

if date3.between(date1, second: date4)  {...}

let date = date1.closest(date3, second: date4)    // return date3

Modify date

let newDate = date.addYears(1)
let newDate = date.subYears(1)

let newDate = date.addMonths(9)
let newDate = date.subMonths(1)

let newDate = date.addDays(11)
let newDate = date.subDays(11)

let newDate = date.addHours(1)
let newDate = date.subHours(1)

let newDate = date.addMinutes(15)
let newDate = date.subMinutes(15)

let newDate = date.addSeconds(1)
let newDate = date.subSeconds(15)


let newDate = date.addYears(1).addMonths(9).addSeconds(1)

let newDate = date.next()     //nextDay
let newDate = date.previous() //prevDay

let newDate = date.inTimeZone(NSTimeZone(abbreviation: "MSK")!)
let newDate = date.startOfDay()

let newDate = date.endOfDay()
let newDate = date.startOfMonth()

let newDate = date.endOfMonth()
let newDate = date.startOfYear()

let newDate = date.endOfYear()
let newDate = date.average(anotherDay)

Get difference between date

let newDate = firstDate.diffInYears(secondDate)
let newDate = firstDate.diffInMonths(secondDate)

let newDate = firstDate.diffInWeeks(secondDate)
let newDate = firstDate.diffInDays(secondDate)

let newDate = firstDate.diffInHours(secondDate)
let newDate = firstDate.diffInMinutes(secondDate)

let newDate = firstDate.diffInSeconds(secondDate)
