Hi, This email is related to Mongo project [1]. As MongoDb documentation [2] states: "BSON has a special timestamp type for *internal* MongoDB use and is not
associated with the regular Datetype. Timestamp values are a 64 bit value where: - the first 32 bits are a time_t value (seconds since the Unix epoch) - the second 32 bits are an incrementing ordinal for operations within a given second."
Now, our Mongo bindings [1] convert this MongoDb's internal type to Pharo's TimeStamp (i.e. the subclass of DateAndTime) with two problems: - it's a wrong: the 2 parts of 32 bits are converted as 64 bits of milliseconds - it produces a warning in latest Pharo [3]: TimeStamp has been removed so extension methods cannot be installed. That's why I'm creating MongoTimeStamp, and changing BSON marshaling from: BSON>>nextTimestamp ^self nextDateAndTime asTimeStamp to: BSON>>nextTimestamp ^MongoTimeStamp value: self nextInt64 (similar for writing). This solution was idea of Esteban and Norbert, and discussed in the issue tracker of Voyage [3]. Mongo talk team, please tell me if you don't agree.
