Datetime

Datetime

In Swift, dates are handled in Date class. But It was not simple enough to use for us. So LeagueAPI uses a new type that wrappes Date type and provide a more user-friendly interface. The wrapped Data variable is still accessible as read-only in Datetime instances.

Computed Properties

The new Datetime type exposes computed properties:

• year: Int
• month: Int
• day: Int
• hour: Int
• minute: Int
• second: Int
• monthName: String
• weekday: String
• weekdayIndex: Int

Initializers

Datetime contains multiple init methods to create instances:

• Datetime()
• Datetime(date: Date)
• Datetime(timestamp: Long)
• Datetime?(year: Int, month: Int, day: Int, hour: Int = 0, minute: Int = 0, second: Int = 0, timeZone: TimeZone? = nil)
• Datetime?(dateTime: Datetime, timeZone: TimeZone)
• Datetime?(string: String, format: String)

Datetime()

Initialize a new Datetime object with current time.

Datetime(date: Date)

Initialize a new Datetime object with date time

Datetime(timestamp: Long)

Initialize a new Datetime object with a number of seconds milliseconds since 01/01/1970.

Datetime?(year: Int, month: Int, day: Int, hour: Int = 0, minute: Int = 0, second: Int = 0, timeZone: TimeZone? = nil)

Initialize a new Datetime object, specifying date components. Only year, month and day are required.

Datetime?(dateTime: Datetime, timeZone: TimeZone)

Initialize a new Datetime object from another datetime, only changing parameter's timezone.

Datetime?(string: String, format: String)

Initialize a new Datetime object from a String corresponding to format format. format is a String composed of DateToken.Tokens and respecting valid date rule:

• One Year4Digits ("yyyy")
• One MonthDigits/MonthShort/MonthLong ("MM"/"MS"/"ML")
• One DayDigits ("dd")
• At most one "HourDigits" ("hh")
• At most one "MinuteDigits" ("mm")
• At most one "SecondDigits" ("ss")

Here is a usage example:

Datetime(string: "2018/08/23T00:19:00 (Custom Format)", format: "yyyy/MM/ddThh:mm:ss (Custom Format)")

Date Tokens

With dates, a frequent usage is to print it on console. Datetime provide a toString(format: String) method for this. Default format is "yyyy/MM/dd hh:mm:ss", which will be for instance: 2018/08/24 01:05:00. Just like Datetime?(string: String, format: String), you can build a String containing DateToken.Tokens, with no limitation for occurence number. "yyyyyyyy" would print "20182018" for example. DateToken.Tokens are String so you can build the String with enum's rawValue but here's the list:

• Year4Digits = "yyyy", year on 4 digits. Example: 2018
• Year2Digits = "yy", year on 2 digits (last digits of Year4Digits). Example: 18
• MonthDigits = "MM", month on 2 digits. Example: 08
• DayDigits = "dd", day on 2 digits. Example: 24
• HourDigits = "hh", hours on 2 digits: Example: 01
• MinuteDigits = "mm", minutes on 2 digits: Example: 05
• SecondDigits = "ss", seconds on 2 digits: Example: 00
• MonthShort = "MS", first three characters of english month's name. Example: Aug
• MonthLong = "ML", english month's name. Example: August
• DayShort = "dS", first three characters of english day of the week name. Example: Fri
• DayLong = "dL", english day of the week name. Example: Friday Any other characters will be in the resulting String.
