expired timestamp issue during chunk upload. Not getting any help

Hi,

I am getting timestamp expired error. I had raised this problem in earlier thread, but no resolution. Can someone look into it please...

FYI : I am uploading file in chunk, and in this approach I have to set timestamp before I start to upload in chunks. Is this the reason why timestamp is expiring? How to resolve this.
