java dateformat gmt_没有Java时区偏移的SimpleDateFormat(自定义时区的GMT + 00:00))

不是一个优雅的解决方案，但它适用于我们。我不得不为DateFormat / SimpleDateFormat创建一个自定义实现。这看起来如下：

static {

// this would be initialized like something as follows when the application starts

// which causes the headaches of SimpleDateFormat not to work...

SimpleTimeZone tz = new SimpleTimeZone(0, "Out Timezone");

TimeZone.setDefault(tz);

}

// therefore this class will workaround the issue,

public class OurOwnCustomDateFormat

extends SimpleDateFormat {

/** The pattern to use as the format string. */

protected String pattern;

public OurOwnCustomDateFormat(String pattern) {

super(pattern);

// store the pattern

this.pattern = pattern;

}

@Override

public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition pos) {

// custom implementation to format the date and time based on our TimeZone

toAppendTo.insert(pos.getBeginIndex(), "the date with our custom format calculated here");

return toAppendTo;

}
