Module Name:
imgdt.cpp
Abstract:
Tool to manipulate the link date/time
stamp in binaries
NOTE : For I386/IA64 binaries only.
MappedFile abstracts the mapped binary
file in the memory and has methods to
get and set link datetime stamp. While
setting the datetime stamp it also
recomputes and updates the new checksum.
