how to convert date_modified value to datetime

[Tom.Zhang]

when get response form http server with parameters: json=1&date_modified_column=1, i will get infomation like this:

{ "type":"folder", "name":"1226093 backup", "path":"XXXXXXXX", "date_modified":"130912446856077666" }

the question is how to convert 130912446856077666 to normal date time like M/d/yyyy hh:mm:ss, seems it is not the seconds from 1970/01/01.

Thanks!

Dates are FILETIMEs (100-nanosecond intervals since January 1, 1601.) - like EFU format.
