记一次时间查询转UTC时间筛选不正确的问题

 if (startTime != null)
 {
     startTime = startTime.Value.Date.ToUniversalTime();
  　 query = query.Where(p => p.CreatedOnUtc >= startTime);
 }

if (endTime != null)
{
　　endTime = endTime.Value.AddDays(1).Date.ToUniversalTime();
   query = query.Where(p => p.CreatedOnUtc < endTime);
}
