java time  I should like to contribute the modern answer       String ts   String valueOf Instant now   getEpochSecond         System out println ts     Output when running just now      1543320466   While division by 1000 won   t come as a surprise to many  doing your own time conversions can get hard to read pretty fast  so it   s a bad habit to get into when you can avoid it   The Instant class that I am using is part of java time  the modern Java date and time API  It   s built-in on new Android versions  API level 26 and up  If you are programming for older Android  you may get the backport  see below  If you don   t want to do that  understandably  I   d still use a built-in conversion       String ts   String valueOf TimeUnit MILLISECONDS toSeconds System currentTimeMillis          System out println ts     This is the same as the answer by sealskej  Output is the same as before   Question  Can I use java time on Android   Yes  java time works nicely on older and newer Android devices  It just requires at least Java 6    In Java 8 and later and on newer Android devices  from API level 26  the modern API comes built-in  In non-Android Java 6 and 7 get the ThreeTen Backport  the backport of the new classes  ThreeTen for JSR 310  see the links at the bottom   On  older  Android use the Android edition of ThreeTen Backport  It   s called ThreeTenABP  And make sure you import the date and time classes from org threeten bp with subpackages    Links   Oracle tutorial  Date Time explaining how to use java time  Java Specification Request  JSR  310  where java time was first described  ThreeTen Backport project  the backport of java time to Java 6 and 7  ThreeTen for JSR-310   ThreeTenABP  Android edition of ThreeTen Backport Question  How to use ThreeTenABP in Android Project  with a very thorough explanation

This code is Kotlin version  I have another idea to add a random shuffle integer in last digit for giving variance epoch time   Kotlin version  val randomVariance    0  100  shuffled   first   val currentEpoch    System currentTimeMilis   1000    randomVariance  val deltaEpoch   oldEpoch - currentEpoch   I think it will be better using this kode then depend on android version 26 or more

I suggest using Hits s answer  but adding a Locale format  this is how Android   Developers recommends   try           SimpleDateFormat dateFormat   new SimpleDateFormat  yyyy-MM-dd HH mm ss   Locale getDefault             return dateFormat format new Date        Find todays date       catch  Exception e            e printStackTrace             return null

From developers blog   System currentTimeMillis   is the standard  wall  clock  time and date  expressing milliseconds since the epoch  The wall clock can be set by the user or the phone network  see setCurrentTimeMillis long    so the time may jump backwards or forwards unpredictably  This clock should only be used when correspondence with real-world dates and times is important  such as in a calendar or alarm clock application  Interval or elapsed time measurements should use a different clock  If you are using System currentTimeMillis    consider listening to the ACTION TIME TICK  ACTION TIME CHANGED and ACTION TIMEZONE CHANGED Intent broadcasts to find out when the time changes
