have the same problem
{“errors”:[{“message”:“Bad Authentication data”,“code”:215}]}
curl -X GET -H “Authorization: OAuth oauth_nonce=“OAUTH_ONCE”, oauth_timestamp=“1355389805”, oauth_version=“1.0”, oauth_consumer_key=“CONSUMER_KEY”, oauth_signature=“SIGNATURE”, oauth_signature_method=“HMAC-SHA1”, oauth_callback=“rstwitterengine%3A%2F%2Fauth_token””
and it is strange, cause epochconverter.com said to me, that oauth_timestamp is NOW date
