sn.exe delay signing

[Sunny]

Hi,
is this expected behaviour:

I have created a delaysigned assemblies.

After that I signed them with sn -R. But what surprises me is that the
file time stamp is not changed, even the file was.

Is this normal? I would expect to know that the file is altered at
different time, why sn.exe is not updating the time stamp?

Hi Sunny,

Now I am researching the issue, and I will get back here and update you
with new information ASAP.

Hi Sunny,

Sorry for delay response.
I have consulted our product team, Sn.exe -R (and sn.exe -Rc) resign an
assembly so they do indeed change the signature. However, sn.exe uses the
file mapping APIs to directly write into the PE image so the timestamp does
not get modified during that process.

Hi Sunny,

Yes, this is by design and it should be the intended behavior.
