When running siduction live or installing on a windoze computer, the clock may be off (may use UTC as local time). This can result in updates not working because the repos are not yet valid, and the install may abort for this reason.
mxlinux syncs the clock and does not have this problem.
It's not easy for the user to fix this as ntp and other time services are not running by default in the live.
I suggest either syncing the clock or documenting this and showing user how to easily fix.
Also install could force updates to work even if time is out of sync.
