Android的如何获得设备的时间并不时区时间 [英] Android how to get device's time not timezone time
问题描述
我的情况是:用户设置时区以 UTC + 5
,例如,然后关闭时间和时区同步。当他去 UTC + 4
时区,他刚刚成立的时候回一小时,不接触时区。
My case is: user set timezone to UTC+5
, for example, and then turn off time and timezone sync. When he goes to UTC+4
timezone, he just set the time back to an hour, without touching timezone.
所以 Calendar.getInstance()
和 System.currentTimeMillis的()
返回时间 UTC + 5
,例如,14:00,但该设备显示13:00。
So the Calendar.getInstance()
and System.currentTimeMillis()
return the time for UTC+5
, for example, 14:00, but the device shows 13:00.
我怎样才能获得设备的时间和当前时区时间之间的设备时(13:00)或区别?
How can I get the device time(13:00) or difference between device time and current timezone time?

所有我能找到,这里保存在这个<一个href=\"https://pristalovpavel.word$p$pss.com/2015/08/13/how-to-get-the-real-device-time-with-wrong-time-zone/\"相对=nofollow>帖子。
All that I could find, kept here in this post.
<强>摘要强>:这是不可能得到没有额外的查询的服务器和/或接收自己的坐标(其可能不总是可用的)
Summary: it is impossible to obtain the necessary time difference with no additional queries to the server and / or receiving your own coordinates (which may not always be available).
这也适用于取消夏令时:一些设备还认为,在莫斯科的夏天时区 GMT + 4
,另一部分人都知道它的 GMT + 3
。你不能在本地同步本地这些设备一般。
This also applies to canceled daylight time: some devices still believes that in the summer time zone of Moscow is GMT+4
, other part knows that it's GMT+3
. And you can not locally sync these devices locally, in general.
