When producing an oauth_timestamp for any method requiring authentication, the time needs to be indicated in seconds since the "UTC epoch" -- some programming languages have Date & Time classes that deal with epoch time easily for you, others require more work. In any case, when generating an oauth_timestamp, you need to take your local time, convert it to UTC, and then calculate epoch seconds in that timezone. Further, the timestamp needs to be within ~ 5 minutes of Twitter's server clock. Our server clock is reported in the "Date" HTTP header response to each of your requests.
