AWS - Secure REST Query Tool

I need a desktop tool to take as input my: AWS Access Key ID AWS Secret Access Key ...generate a signed query for GetReviewableHITs operation: The example retrieves 100 of Requester's reviewable HITs, with default value for SortOrder param (Ascending). [login to view URL] &AWSAccessKeyId=[the Requester's Access Key ID] &Version=2008-08-02 &Operation=GetReviewableHITs &Signature=[signature for this request] &Timestamp=[your system's local time] &SortProperty=Enumeration &PageSize=100 &PageNumber=1 Reference: [login to view URL] ...and repeat until all reviewable HITs retrieved. Reference: [login to view URL] ...then output HITId's, one per line, for copy and paste into Excel: <GetReviewableHITsResult> <Request> <IsValid>True</IsValid> </Request> <NumResults>1</NumResults> <TotalNumResults>1</TotalNumResults> <PageNumber>1</PageNumber> <HIT> <HITId>GBHZVQX3EHXZ2AYDY2T0</HITId> <HITId>27ZM8JIA0RYNYL64CTD0C</HITId> <HITId>29HVXX2Q45UUZ2SF9W9W</HITId> <HITId>L64CT8NS8PIHR988DJIA0R</HITId> <HITId>2C79746OQ1SN52B7ZGR58</HITId> <HITId>QKCTL988DN3X2Q45UU2SF</HITId> </HIT> </GetReviewableHITsResult> NOTE: I do not want all the XML returned, for the sample above, the GUI output: GBHZVQX3EHXZ2AYDY2T0 27ZM8JIA0RYNYL64CTD0C 29HVXX2Q45UUZ2SF9W9W L64CT8NS8PIHR988DJIA0R 2C79746OQ1SN52B7ZGR58 QKCTL988DN3X2Q45UU2SF I'm not sure about timestamp, does it need my local computer time, or time of server routing my request?
