Edit to add: This is in regards to the UC320W with most recent firmware.
A timely question. In most of the USA the change to daylight savings time occurs at 2:00AM Sunday morning. At 2:00AM it will become 3:00AM DST. If "use daylight savings?" and "enable USB backup?" are checked and left at default values, and scheduled maintenance is left at it's default value, it is unclear if a problem will occur. The default time for a scheduled backup to a USB is 2:00 AM Sunday, and the default reboot time is 3:00AM Sunday. Do I need to change the scheduled times before this weekend? Or does it somehow work anyway? Thank You.
