Boto interfacing to Amazon Mechanical turk - Hit creation

241 views Asked by At

I'm new to amazon and python, so forgive me this is a easy fix. Upon creating a hit from boto I get the following error:

boto.mturk.connection.MTurkRequestError: MTurkRequestError: 200 OK

<?xml version="1.0"?>
<GetAssignmentsForHITResponse><OperationRequest><RequestId>17449b9f-b1f3-4d54-bbbd-974210ce1c1b</RequestId><Errors><Error><Code>AWS.BadClaimsSupplied</Code><Message>The specified claims are invalid.

Check to make sure your system clock and timezone is not incorrect.  Our current system time: 2014-01-06T22:20:05Z.

From my understanding the problem is an inconsistency between my system's clock and the amazon system clock. I've tried synchronizing the clock right before i create a hit but the error persists.

Notes: this time the times match perfectly but there has been instances where they were 1 to 3 seconds apart! if it helps at all, this is part of implementing crowdforge that Im having trouble with.
