Java: Date from unix timestamp
For 1280512800, multiply by 1000, since java is expecting milliseconds:
java.util.Date time=new java.util.Date((long)timeStamp*1000);If you already had milliseconds, then just new java.util.Date((long)timeStamp);
From the documentation:
Allocates a Date object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.
java.time
Java 8 introduced a new API for working with dates and times: the java.time package.
With java.time you can parse your count of whole seconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00Z. The result is an Instant.
Instant instant = Instant.ofEpochSecond( timeStamp );If you need a java.util.Date to interoperate with old code not yet updated for java.time, convert. Call new conversion methods added to the old classes.
Date date = Date.from( instant );
