Check that the time on your server matches the time of Twitter's servers. If they are different by more then 5 minutes Twitter will refuse your connection.

My server timezone is(Amirica/New york). How i can find twitter server time?

[abraham]

How to get the time returned from Twitter. If your server is more then 5 minutes out of sync requests will fail.
$connection->http_header['date']

As I said your servers time is different from Twitter's. Looking here it is off by about 22 minutes.

Twitter's time: Sun, 05 Sep 2010 16:30:01 GMT aka 1283704201
Your servers time: 1283702864
A difference of 1337 seconds or just over 22 minutes.

Look into using NTP to sync your servers time correctly.

[anupamabhadani]

I have no access to change my server time, if i can use date_default_timezone_set() for setting the time zone. what time zone i must pass as the param and if it will work.

[anupamabhadani]

date_default_timezone_set() it is not working, can u suggest how to resolved this problem

[abraham]

Setting the timezone will not help. You have to change the time (hour/minutes/second) of the server. Get in contact with your server administrator or hosting provider to enable NTP syncing.
