我想要获取UTC的当前时间。到目前为止,我所做的事情如下(仅用于测试目的):
DateTime dt = new DateTime();
DateTimeZone tz = DateTimeZone.getDefault();
LocalDateTime nowLocal = new LocalDateTime();
DateTime nowUTC = nowLocal.toDateTime(DateTimeZone.UTC);
Date d1 = nowLocal.toDate();
Date d2 = nowUTC.toDate();
L.d("tz: " + tz.toString());
L.d("local: " + d1.toString());
L.d("utc: " + d2.toString());d1是我的本地时间,也就是fined2是我的本地时间+ 1,但应该是本地时间- 1...我的本地时区是UTC+1 (根据调试输出和这里的列表:https://www.joda.org/joda-time/timezones.html)...
如何正确地从一个时区转换到另一个时区(包括毫秒表示)?

我需要日期/毫秒...这不是关于正确显示时间的问题...

现在,在一条评论和一个答案的帮助下,我尝试了以下内容:
DateTimeZone tz = DateTimeZone.getDefault();
DateTime nowLocal = new DateTime();
LocalDateTime nowUTC = nowLocal.withZone(DateTimeZone.UTC).toLocalDateTime();
DateTime nowUTC2 = nowLocal.withZone(DateTimeZone.UTC);
Date dLocal = nowLocal.toDate();
Date dUTC = nowUTC.toDate();
Date dUTC2 = nowUTC2.toDate();
L.d(Temp.class, "------------------------");
L.d(Temp.class, "tz : " + tz.toString());
L.d(Temp.class, "local : " + nowLocal + " | " + dLocal.toString());
L.d(Temp.class, "utc : " + nowUTC + " | " + dUTC.toString()); // <= WORKING SOLUTION
L.d(Temp.class, "utc2 : " + nowUTC2 + " | " + dUTC2.toString());输出
tz : Europe/Belgrade
local : 2015-01-02T15:31:38.241+01:00 | Fri Jan 02 15:31:38 MEZ 2015
utc : 2015-01-02T14:31:38.241 | Fri Jan 02 14:31:38 MEZ 2015
utc2 : 2015-01-02T14:31:38.241Z | Fri Jan 02 15:31:38 MEZ 2015我想要的是,本地日期显示15点,utc日期显示14点……现在,这似乎是可行的.
- EDIT3 -最终解决方案-
希望这是一个很好的解决方案。我想,我尊重我得到的所有小费...
DateTimeZone tz = DateTimeZone.getDefault();
DateTime nowUTC = new DateTime(DateTimeZone.UTC);
DateTime nowLocal = nowUTC.withZone(tz);
// This will generate DIFFERENT Dates!!! As I want it!
Date dLocal = nowLocal.toLocalDateTime().toDate();
Date dUTC = nowUTC.toLocalDateTime().toDate();
L.d("tz : " + tz.toString());
L.d("local : " + nowLocal + " | " + dLocal.toString());
L.d("utc : " + nowUTC + " | " + dUTC.toString());输出:
tz : Europe/Belgrade
local : 2015-01-03T21:15:35.170+01:00 | Sat Jan 03 21:15:35 MEZ 2015
utc : 2015-01-03T20:15:35.170Z | Sat Jan 03 20:15:35 MEZ 2015https://stackoverflow.com/questions/27741288
