将DateTime插入MongoDB

Question

Is there something which I need to take into consideration when Im trying to serialize data into Mongo database which is keyed by DateTime?

My data looks like this SortedDictionary<DateTime, Data> Data and the problem Im facing is that the DateTime key have time part equal to 00:00:00 but after insertion into Mongo it is ISODate("2003-11-24T23:00:00Z") sometimes T22:00:00Z . I preaty sure the problem is not with data Im inserting into DB I checked on every possible place if time part is always equal to 00:00:00 and it is.

Answer 1

mongo默认以UTC格式存储日期，因此您似乎处于不同的时区，因此有所不同

Answer 2

Are you converting from a string to a datatime in C#? Maybe that is causing it to be off by an hour because of daylight savings, local time, or UTC.

The C# mongodb driver handles the format. You could quickly test using something like an integer to be sure it's not your format prior to insertion. MongoDB DateTime Format
