Welcome Zachery,
Thanks for the details and screenshots, and for trying SFC and the timedate.cpl workaround already. I understand you want the clock to stop changing now that British Columbia no longer follows daylight saving time.
Before we start, please confirm:
- Is this a personal computer with a personal Microsoft account or local account? Or is it a work or school computer, or managed by an organization?
- Does Settings > Accounts > Your info show Administrator under your account name?
Looking forward to your update.
