java.lang.NumberFormatException: For input string:

I'm trying to convert a String timestamp to an Integer one and I'm using
postgres as DB.
@Column(name = "connecte_timestamp")
private Integer timestamp;
SimpleDateFormat formater = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss");
Date aujourdhui = new Date();
this.timestamp = Integer.parseInt(formater.format(aujourdhui)
.replace("-", "").replace(" ", "").replace(":", ""));
the timestamp have bigint as a type in the DB. When I run my app, I get
the following stack trace :
java.lang.NumberFormatException: For input string: "01092013062024" at
