means that the IDT contains fixed addresses for imported functions
using bound imports is a speed optimization. reduces time needed by loader to resolve function addressess and fill the IAT.
If however, at run-time the bound addressess do not match the real ones. the loader has to resolve these on its own and fix the IAT
If the TimeDateStamp or another bound-based field is set to an unusual value, the real value can be found in the Bound Import Data Directory
