在date.gettime()中获得负值 [英] Getting negative value in date.gettime()

问题描述

面对一个问题，其中我试图将字符串值解析为date，而当我尝试进行date.getTime()时，我得到的是负值.

Facing an issue where I am trying to parse a string value into date and when I try to do date.getTime() I am getting negative value.

这是我正在解析的字符串"01:00:07".这是日期对象中的值，我得到的是"Thu Jan 01 01:00:07 GMT + 05:30 1970".仍然在getTime()中，我得到的是负值"-16193000"

This is the string I am parsing "01:00:07". and this is the value in date object I get "Thu Jan 01 01:00:07 GMT+05:30 1970". Still in getTime() I am getting negative value "-16193000"

实现此目的的代码:

long sum = 0;
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm:ss");// I have also tried "HH:mm:ss" format. it gives same result
    Date date = simpleDateFormat.parse(duration);//duration is "01:00:07"
    sum= date.getTime();

推荐答案

问题是 TimeZone .通过提供 TimeZone

simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));

或

simpleDateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
