以下作品(显示UTC时间)
The following works (shows UTC time)
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
System.out.println(new Date());
但这不(显示当地时间)
but this doesn't (shows local time)
Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal.getTime());
System.out.println(new Date());
有什么简单的东西我错过了吗?
Is there something simple, that I'm missing?
您正在打印 Date.toString()
,总是使用默认时区.
You're printing out the result of Date.toString()
, which always uses the default time zone.
我建议你使用 DateFormat
相反,它更适合格式化日期.Date.toString
实际上只适用于调试 - 它无法控制格式.
I suggest you use DateFormat
instead, which is better suited for formatting dates. Date.toString
is really only suitable for debugging - it provides no control over the format.
或者,使用 Joda Time 进行所有日期和时间操作 - 这是一个更好的 API 开始:)
Alternatively, use Joda Time for all your date and time operations - it's a much better API to start with :)
