In java 8, it's convenient to use the new date lib and getEpochSecond
method to get the timestamp (it's in second)
Instant.now().getEpochSecond();
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.TimeZone;
public class Timeconversion {
private DateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmm", Locale.ENGLISH); //Specify your locale
public long timeConversion(String time) {
long unixTime = 0;
dateFormat.setTimeZone(TimeZone.getTimeZone("GMT+5:30")); //Specify your timezone
try {
unixTime = dateFormat.parse(time).getTime();
unixTime = unixTime / 1000;
} catch (ParseException e) {
e.printStackTrace();
}
return unixTime;
}
}
I dont know if you want to achieve that in js or java, in js the simplest way to get the unix timestampt (this is time in seconds from 1/1/1970) it's as follows:
var myDate = new Date();
console.log(+myDate); // +myDateObject give you the unix from that date
Use SimpleDateFormat
class. Take a look on its javadoc: it explains how to use format switches.
To get a timestamp
from Date()
, you'll need to divide getTime()
by 1000
, i.e. :
Date currentDate = new Date();
currentDate.getTime() / 1000;
// 1397132691
or simply:
long unixTime = System.currentTimeMillis() / 1000L;
