How to convert the epoch time to time stamp in talend - talend

Question

For suppose we have 166667777 of file then we want to convert into time stamp how to convert it in talend

Answer 1

in a tjava just paste this code :
Date myDate= new Date(Long.parseLong("1081157732") * 1000);
System.out.println(myDate) ;
SimpleDateFormat jdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String java_date = jdf.format(myDate);
System.out.println(java_date) ;
Since you didn't tell us your pattern just see what fits your requirement in the console
Don't forget this import in advanced settings :
import java.util.*;
import java.text.SimpleDateFormat ;
Here is the output :
[statistics] connected
Mon Apr 05 11:35:32 CEST 2004
2004-04-05 11:35:32
[statistics] disconnected
If you are wanting to get the the actual timestamp here how it is done
put in the tJava :
long epoch = Instant.now().toEpochMilli();
System.out.println(epoch);
LocalDate ld = Instant.ofEpochMilli(epoch).atZone(ZoneId.systemDefault()).toLocalDate();
System.out.println(ld);
LocalDateTime ldt = Instant.ofEpochMilli(epoch).atZone(ZoneId.systemDefault()).toLocalDateTime();
System.out.println(ldt);
And as always don't forget the import :
import java.text.SimpleDateFormat ;
import java.time.Instant;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.ZoneId;
your output would be :
[statistics] connected
1638973017921
2021-12-08
2021-12-08T15:16:57.921
[statistics] disconnected
