Error getting HTTP response

gdata-client-1.0-1.41.3
gdata-core-1.0-1.41.3
google-collections-1.0-rc1
gdata-contacts-3.0-1.41.3
Java 1.6

If I run the code below (using either RSA and HMAC) on my development Windows 
XP laptop (java 1.6.0.20) it works.    However, if I run the exact same code on 
my production Linux server (1.6.0.06), it fails with the error:  "Error getting 
HTTP response".  This exception is being raised on the following line:

com.google.gdata.client.authn.oauth.OAuthException: Error getting HTTP response
        at com.google.gdata.client.authn.oauth.OAuthHttpClient.getResponse(OAuth
HttpClient.java:76)

Any clues?

Any ideas or comments about this error?

This problem was due to incorrect timestamp on my Linux server.  My timestamp 
was 27 minutes behind what it should actually be.  I modified the date 
timestamp, and started the ntpd (network timing syncronization) daaemon.  And 
that fixed the issues I was having with Google OAuth 400 HTTP response error.

Again, if you have this problem where the exact same OAuth code works on one 
box, but does not work on another.  Please, *ensure* the timestamp of your 
other box is not too far from what it should be.

Thanks,
