Android Get Current timestamp?

The solution is :

Long tsLong = System.currentTimeMillis()/1000;
String ts = tsLong.toString();

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.

1320917972 is Unix timestamp using number of seconds since 00:00:00 UTC on January 1, 1970. You can use TimeUnit class for unit conversion - from System.currentTimeMillis() to seconds.

String timeStamp = String.valueOf(TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis()));

You can use the SimpleDateFormat class:

SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String format = s.format(new Date());
