Run aws s3 ls to confirm whether the error is related to time sync. You should get the error like:

An error occurred (RequestTimeTooSkewed) when calling the ListBuckets operation: The difference between the request time and the current time is too large.

If so, try to sync your datetime as suggested.

Example shell commands on Linux to do that:

# Install the ntpdate client for setting system time from NTP servers.
sudo apt-get --yes install ntpdate
sudo ntpdate 0.amazon.pool.ntp.org

Then re-try your aws command again.

If the timezone is still not correct, run: sudo dpkg-reconfigure tzdata to configure it, or by:

timedatectl list-timezones
timedatectl set-timezone 'Europe/London'
