无能为力，不会java，帮你顶一下

Answer 2

给你简单写了个实现日期+8区和格林威治时间互转。 public Date DateTimeToGeneralizedTime(Date date){
Calendar cal = Calendar.getInstance();
cal.setTime(date);
TimeZone.setDefault(TimeZone.getTimeZone("GMT+0"));
return cal.getTime();
} public Date GeneralizedTimeToDateTime(Date date){
Calendar cal = Calendar.getInstance();
TimeZone.setDefault(TimeZone.getTimeZone("GMT+0"));
cal.setTime(date);
TimeZone.setDefault(TimeZone.getTimeZone("GMT+8"));
return cal.getTime();
}
