推荐答案

接受的答案不正确处理设置了秒或毫秒的数据时间。为了完整，这里是一个正确处理的版本：

The accepted answer doesn't correctly handle datetimes that have seconds or milliseconds set. For completeness, here's a version that does handle that correctly:

private DateTime roundDate(final DateTime dateTime, final int minutes) { if (minutes < 1 || 60 % minutes != 0) { throw new IllegalArgumentException("minutes must be a factor of 60"); } final DateTime hour = dateTime.hourOfDay().roundFloorCopy(); final long millisSinceHour = new Duration(hour, dateTime).getMillis(); final int roundedMinutes = ((int)Math.round( millisSinceHour / 60000.0 / minutes)) * minutes; return hour.plusMinutes(roundedMinutes); }
