Cconvert NSTimeInterval milisecondedDate value to nsstring and after that convert into int

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

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

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

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

As mentioned before     NSDate date  timeIntervalSince1970  returns an NSTimeInterval  which is a duration in seconds  not milli-seconds   You can visit https   currentmillis com  to see how you can get in the language you desire  Here is the list -  ActionScript     new Date    time C   std  chrono  duration cast lt std  chrono  milliseconds gt  std  chrono  system clock  now   time since epoch    count   C  NET  DateTimeOffset UtcNow ToUnixTimeMilliseconds   Clojure  System currentTimeMillis  Excel   Google Sheets      NOW   - CELL WITH TIMEZONE OFFSET IN HOURS 24 - DATE 1970 1 1     86400000 Go   Golang time Now   UnixNano     1000000 Hive    unix timestamp     1000 Java   Groovy   Kotlin  System currentTimeMillis   Javascript  new Date   getTime   MySQL   UNIX TIMESTAMP     1000 Objective-C  long long    NSDate date  timeIntervalSince1970    1000 0  OCaml    1000 0    Unix gettimeofday     Oracle PL SQL   SELECT  SYSDATE - TO DATE  01-01-1970 00 00 00    DD-MM-YYYY HH24 MI SS      24   60   60   1000 FROM DUAL Perl    use Time  HiRes qw gettimeofday   print gettimeofday  PHP round microtime true    1000  PostgreSQL  extract epoch FROM now      1000 Python  int round time time     1000   Qt  QDateTime  currentMSecsSinceEpoch   R   as numeric Sys time      1000 Ruby     Time now to f   1000  floor Scala   val timestamp  Long   System currentTimeMillis SQL Server  DATEDIFF ms   1970-01-01 00 00 00   GETUTCDATE    SQLite  STRFTIME   s    now     1000 Swift   let currentTime   NSDate   timeIntervalSince1970   1000 VBScript   ASP  offsetInMillis   60000   GetTimeZoneOffset   WScript Echo DateDiff  s    01 01 1970 00 00 00   Now      1000 - offsetInMillis   Timer   1000 mod 1000   For objective C I did something like below to print it -  long long mills    long long    NSDate date  timeIntervalSince1970    1000 0    NSLog   Current date  lld   mills     Hopw this helps
