Swift gets Current timestamp (sec, millisecond)

It is often seen that a second-level timestamp is obtained in the form of an Int type direct * 1000来 MS, so that the final 3 digits are 0, and the results are not accurate enough. So there's another way to get a millisecond timestamp. Create a Date Extension with the following code

    Extension Date {

    ///gets the current second-level timestamp-10-bit
    var timestamp:string {let
        timeinterval:timeinterval = Self.timeinte rvalSince1970 let
        timeStamp = Int (timeinterval) return
        "\ (TimeStamp)"

    ///Obtain the current millisecond timestamp-13-bit
    var millistamp:string {let
        timeinterval:timeinterval = self.timeintervalsince1970 let
        millisecond = CLongLong ( Round (timeinterval*1000)) return
        "\ (Millisecond)"
 Let millisecond = Date (). Millistamp
 Print (the current millisecond timestamp is millisecond = =, millisecond) let
 timeStamp = Date (). TimeStamp
 Print (the current second-level timestamp is timeStamp = =, TimeStamp)

    The current millisecond timestamp is millisecond =  1524801851988
    The current second-level timestamp is TimeStamp = =  1524801851
