An extension on date is probably the best way to about it     extension NSDate       func msFromEpoch   - gt  Double           return self timeIntervalSince1970   1000

You can just do this   long currentTime    long  NSTimeInterval    NSDate date  timeIntervalSince1970      this will return a value en milliseconds  so if you multiply the resulting value by 1000  as suggested my Eimantas  you ll overflow the long type and it ll result in a negative value   For example  if I run that code right now  it ll result in  currentTime   1357234941   and   currentTime  seconds   minutes   hours   days   years 1357234941   60   60   24   365   43 037637652207

There are several ways of doing this  although my personal favorite is    CFAbsoluteTime timeInSeconds   CFAbsoluteTimeGetCurrent      You can read more about this method here  You can also create a NSDate object and get time by calling timeIntervalSince1970 which returns the seconds since 1 1 1970   NSTimeInterval timeInSeconds     NSDate date  timeIntervalSince1970     And in Swift    let timeInSeconds  TimeInterval   Date   timeIntervalSince1970

JavaZava your solution is good  but if you want to have a 13 digit long value to be consistent with the time stamp formatting in Java or JavaScript  and other languages  use this method   NSTimeInterval time      NSDate date  timeIntervalSince1970       returned as a double long digits    long time     this is the first 10 digits int decimalDigits    int  fmod time  1    1000      this will get the 3 missing digits long timestamp    digits   1000    decimalDigits    or  if you need a string    NSString  timestampString    NSString stringWithFormat    ld d  digits  decimalDigits

Casting the NSTimeInterval directly to a long overflowed for me  so instead I had to cast to a long long   long long milliseconds    long long    NSDate date  timeIntervalSince1970    1000 0     The result is a 13 digit timestamp as in Unix
