Android Get Current timestamp?

Question

I want to get the current timestamp like that : 1320917972

int time = (int) (System.currentTimeMillis());
Timestamp tsTemp = new Timestamp(t         


        

Answer 1

Solution in Kotlin:

val nowInEpoch = Instant.now().epochSecond

Make sure your minimum SDK version is 26.

Answer 2

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()));

Answer 3

You can get Current timestamp in Android by trying below code

time.setText(String.valueOf(System.currentTimeMillis()));

and timeStamp to time format

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(Long.parseLong(time.getText().toString())));
time.setText(dateString);

Answer 4

It's simple use:

long millis = new Date().getTime();

if you want it in particular format then you need Formatter like below

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String millisInString  = dateFormat.format(new Date());

Answer 5

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

Answer 6

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.
