将日期转换为时间戳UTC

问题描述：

我是Java新手，想知道如何将日期转换为时间戳，例如

I am new to Java and wanted to know how can I convert date to timestamp like

http://www.timestampconvert.com/?go1=true&m=08&d=06&y=2007&hours=05&min=30&sec=000&Submit=++++++Convert+to+timestamp+++++&offset=-5.5 if I pass a date to it and vice versa..

我在此处在*上进行搜索，但没有一个问题能解决我的问题

I searched here on * but none of the questions have solved my problem

我需要在JSON中使用此时间戳作为highcharts API上的参数来显示点数

I need to use this timestamp in my JSON as a parameter on the highcharts API to show points

要将日期转换为时间戳记:

To convert a date to a timestamp:

String date = "2014-08-03 15:20:10"; //Replace with your value
Timestamp timestamp = Timestamp.valueOf(date);
// Convert timestamp to long for use
long timeParameter = timestamp.getTime();

要将时间戳转换为日期:

To convert a timestamp to a date:

long timeParameter = 1186358400; //Replace with your value
Timestamp timestamp = new Timestamp(timeParameter);
Date date = new Date(timestamp.getTime());
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String textDate = df.format(date); // This gives a string like "2014-08-03 15:20:10"

希望这会有所帮助！
