Clocks do not typically go back by 20 minutes. The standard clock change related to Daylight Saving Time (DST) involves setting clocks back one hour in the autumn and forward one hour in the spring. For example, in the UK, the clocks will go back by one hour on October 26, 2025, at 2:00 AM, marking the end of British Summer Time. In the United States, clocks go back one hour to standard time on November 2, 2025, at 2:00 AM. There is no standard practice of clocks going back by 20 minutes on any official date in 2025 or typically any year. The usual change is one hour backward in autumn and one hour forward in spring for DST adjustments.
If you meant a specific clock or a custom setting, please provide more details, but as per official DST schedules, clocks change by one hour only.
