I run 'ntpdate' at boot time before starting my ntpd daemon.... this updates 
the date to the
correct time so ntpd doesn't complain about any differences. I even have a 
system with a dead CMOS
battery that forgets all its settings if I remove the power lead and it works 
on that system, so
perhaps this may help you?

the time stamps are too far apart then S3 will reject the command.

For example, you can mark a command with an expiration date and time for the 
request. If this time
has passed then S3 will reject a valid request.

Perhaps s3cmd doesn't mark each command this way and Boto does? If that's the 
case then maybe its
not a bug as in "broken code", but just something we need to monitor for and 
display a error
message on when it happens?
