Hi Anat,
Running oauth requests from within a mobile application is not
recommended. We advise that the requests be made from a single
centralized server to ensure sequential timestamp and to protect the
key / secret.
Unfortunately it is not possible to "reset" the timestamp on the
server. The problem will persist until the timestamps are sent in
sequential order by at which stage it will resolve itself once the
timestamps are greater than the last successful request.
