Windows Portable Executable files have a timestamp field and a
checksum field. By default the timestamp field is updated to the
current time, which consequently changes the checksum. This makes the
build nondeterministic. It looks like this:

https://learn.microsoft.com/en-us/windows/win32/debug/pe-format says
that a timestamp of zero can be used to represent a time that is not
"real or meaningful", so we do that.
As far as I can tell, the timestamp and checksum are only used in
DLLs, not directly executed .exe files.
