我写了以下方法：
private static String getDate(final long addToCurrentMillis, final String pattern) {
final long timeMilliseconds = System.currentTimeMillis() + addToCurrentMillis;
final SimpleDateFormat sdf = new SimpleDateFormat(pattern);
final Date resultdate = new Date(timeMilliseconds);
final TimeZone timeZone = TimeZone.getDefault();
sdf.setTimeZone(timeZone);
return sdf.format(resultdate);
}
我使用了"yyyy-MM-dd zzz"模式，结果是：
2015-10-24 EEST
我正在使用此方法进行单元测试。问题是我尝试将此字符串转换回我想要测试的代码中的TimeZone，但TimeZone并不了解EEST时区。有什么想法吗？
答案 0 :(得分：6)
TimeZone.getAvailableIDs不包含EEST
它包含time zone IDs from IANA Time Zone Database，而不是abbreviated time zone names。
要找出每个时区ID的缩写时区名称，请在下面的代码段中运行：
SimpleDateFormat sdf = new SimpleDateFormat("zzz");
Date now = new Date();
for (String id : TimeZone.getAvailableIDs()) {
sdf.setTimeZone(TimeZone.getTimeZone(id));
System.out.println(id + " = " + sdf.format(now));
}
在我当前的机器上（Ubuntu Mint 17.2，JDK 1.8.0_60），输出如下：
