-	Each request to S3 and similar storage services carries a timestamp containing the time at which the request was made.

In some cases the error message won’t indicate that a time difference is the cause of the error but, if you see a message inclusive of this text:\\ \\ ''%%The difference between the request time and the current time is too large%%''\\ \\ you can be sure the cause is that the clock on your SME appliance is out of sync with the clock on your storage service.\\ \\ To fix this problem you need only enable the ntpd service, which keeps the clock on your appliance in sync with a clock on a server that is a reliable time keeper:\\ \\ ''%% \# su - root\ \# systemctl enable ntpd.service\ \# systemctl start ntpd.service%%''\\ \\ S3 and S3 compatible services deal exclusively in Coordinated Universal Time (UTC) for the purpose of comparing request times to the current time. This means that the timezone to which your server is set doesn’t matter. As long as the UTC on your appliance is close to correct, your request should be honoured by the storage service.	+	Each request to S3 and similar storage services carries a timestamp containing the time at which the request was made.
