Timestamp 使用

Timestamp是一个长整形的类型

1.使用方法一

Timestamp nowdate1 = new Timestamp(System.currentTimeMillis());
System.out.println("System.currentTimeMillis():"+nowdate1);

2. 使用方法二

Date date = new Date();
      Timestamp nowdate2 = new Timestamp(date.getTime());
  System.out.println("new Date():"+nowdate2)

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

3. 使用方法三

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  Timestamp nowdate = new Timestamp(System.currentTimeMillis());
  String datestr = sdf.format(nowdate);
  System.out.println(datestr);
