Extracting TimeZone from Mongo Date

Question

I have a date string of the form: "Fri Jun 20 16:14:00 GMT+0530 2014" As you can see there is TimeZone information in the date (GMT+0530).

But once we store this in MongoDB using mongodb 'date' datatype. I see it is stored in a format like this: '2014-06-20 10:44:00.470Z'

How can i extract the 'original' Time Zone from this date??
(I am using Java for storing/extracting data from mongo)

Answer 1

MongoDB使用的BSON Date数据类型只是1970年1月1日以来的毫秒数的64位整数毫秒。因此，如果要跟踪时间戳记的原始时区，则必须将其分开存储，因为转换时它会丢失Date 。

Answer 2

MongoDB stores dates in ISO 8601 format. There's no straight forward way to convert to it from the Java date format, but here's a similar question, look at the accepted answer, it should give you a clue on how to do this.
