> A stamp that is used for different purposes in several places in a PE or COFF file. In most cases, the format of each stamp is the same as that used by the time functions in the C run-time library. For exceptions, see the descripton of IMAGE_DEBUG_TYPE_REPRO (section 6.1.2). If the stamp value is 0 or 0xFFFFFFFF, it does not represent a real or meaningful date/time stamp.
and
> The presence of an entry of type IMAGE_DEBUG_TYPE_REPRO indicates the PE file is built in a way to achieve determinism or reproducibility. If the input does not change, the output PE file is guaranteed to be bit-for-bit identical no matter when or where the PE is produced. Various date/time stamp fields in the PE file are filled with part or all the bits from a calculated hash value that uses PE file content as input, and therefore no longer represent the actual date and time when a PE file or related specific data within the PE is produced. The raw data of this debug entry may be empty, or may contain a calculated hash value preceded by a four-byte value that represents the hash value length.
That and policies like this aren't clear until you sign up.
So you sign a non-compete, but if you ask you get told that things like games or open source contribution are fine.
Then you come in and you find out that internal policy is that you need approval for everything. That's not that unreasonable, and they are usually not too slow. for most things they don't have a blanket ban.
THen you don't quit immediately because you don't want to hand back your signing bonus, but once you it that one year mark it becomes an option and many people do quit at that point.
The reason is it is competition. Amazon makes games, you can't make games. If you want to do any sort of outside development then you have to ask permission, they can shut you down with or without explanation and they currently have a blanket ban on games. Or game engines, or anything related to games.
This includes starting a blog just to talk about game mechanics or the like.
Technically you aren't actually banned from making a game. It's just that you can't ever publish it, show it to anyone, or talk about it.
Of course if you apply you will get told it is no problem to do outside development.
