I have a fortran file say abc.f.
This abc.f has some code inside and defines a module say abcd.
When i compile the file using ifort compiler it creates abcd.mod,and abc.o.
I save these .o and .mod file in another location and recompile the abc.f.
Now when i compare the new abcd.mod with old one it differs, but .o files are same.
What could be the possible reason?
Its a timestamp which is included in the mod files.
