In the past few years, some provinces in Canada have ended the daylight savings system, where the clocks usually moved ahead or back 1 hour, in spring and fall, relatively speaking.
The ending of daylight savings has caused some confusion in how time is calculated over various time zones, where other jurisdictions still retain the daylight savings system.
For Opera users, it can be hard to get your browser to stick to the time you manually set, as I have found out myself.
In my location, daylight savings has ended, so I had to reset my windows system to match the current time.
I live in the Pacific Standard Time (PST) zone. I had to reset Windows 11 to use Mountain Time instead to match the time my area now uses.
Through an extension that saves Tab URLS (Session Buddy), I found the Opera browser was still working on Daylight savings time. That was confusing because the browser is suppose to work from my Windows system time, which I reset to Mountain time. The browser was 1 hour ahead of my system time.
I found the cause.
• In Windows 11, go to Windows > Settings > Time & Language > Date & Time,
• then turn off - "Adjust for daylight saving time automatically".
Close the Opera browser if it is still open.
Reopen the browser and check how the browser reads the time, you will find it is now synced with the Windows system time.
Simply you have to turn off the automated time feature in Windows.
If you live in an area where daylight saving time is ended, setting the time zone on your computer now requires a manual setting and turn off automated settings.
