Question

我正在努力解决一些看似难以置信的问题。如果下面列出的transaction_date（顺便说一下是一个字符串，而我似乎无法将其转换为爱情或金钱的ISODate）是在UTC时间，那我怎么能查询一个月的范围（如果这是一个约会）并总结销售额？

我不想要的是UTC月份，我想要本地时区月份。所以我想我的问题是双重的，

有没有人知道如何将transaction_date转换为ISODate而不是字符串？ $ DateFromString不起作用
如何将查询作为预期的本地时区输入，其中transaction_date存储为UTC日期？

谢谢，马特

使用MongoDB 3.6，您可以使用 ISODate() 并设置时区。这将返回$gt，您可以使用 $lt 或 db.collection.aggregate([{ "$project": { "transaction_date": { "$dateFromString": { "dateString": "$transaction_date", "timezone": "America/New_York" } } } }]) 进行查询：

{
  "_id": ObjectId("5ab485c669150d532c41769f"),
  "transaction_date": ISODate("2018-03-07T16:36:48Z")
}

这将返回

 NSDictionary *dict = @{
                               @"data": @[
                                       @{
                                           @"timings": @{
                                                   @"Sunrise": @"07:14 (PKT)",
                                                   @"Sunset": @"18:15 (PKT)",
                                                   @"Midnight": @"00:45 (PKT)"
                                                   }
                                           },
                                       @{
                                           @"timings": @{
                                                   @"Sunrise": @"07:13 (PKT)",
                                                   @"Sunset": @"06:40 (PKT)",
                                                   @"Midnight": @"00:45 (PKT)"
                                                   }
                                           }
                                       ]
                               };
     NSArray *arrData = [NSArray arrayWithArray:[dict objectForKey:@"data"]];
    [self saveinDatabase:arrData];
