Hi,
I would make sure that your system's clock is within about 5 minutes of
Twitter's. We return our current time in the Date HTTP header of every
response. One easy way to fixate an application's clock with our servers is
to issue a HTTP HEAD request to http://api.twitter.com/1/help/test.xml --
Unless your system does not have access to the Internet, there is no
excuse for not synchronizing its clocks to the world-wide NTP server
pool. Zero - zip - zilch - nada - absolutely no excuse! Five minutes
leeway is not really acceptable.
