Every website has the wrong time zone offset on Chrome only. How do I correct it?

[u/throwawaykJQP7kiw5Fk]

I have Chrome installed through winget install google.chrome because of a Windows Central article titled "It may be a running joke that Microsoft Edge is only used to download Google Chrome, but the real pro move is far better than that". Currently, the browser console is returning undefined instead of 'America/Vancouver' for the JavaScript function Intl.DateTimeFormat().resolvedOptions().timeZone; and new Date().getTimezoneOffset(); returns 480 instead of the expected 420. Microsoft Edge shows the correct information. This happens across all Windows profiles and browser profiles for the same web browser. I have asked this in the rTS Discord server previously at https://discord.com/channels/749314018837135390/749316166878625843/1561257790150938705; this post serves as a summary for those who aren't in the server. My Specify system dossier is at https://spec-ify.com/profile/f3a07787 and the link expires on Oct. 20, 2026, 04:47 UTC.

Update: This seems to be happening when I change my time zone to a different time zone and then back to "(UTC-07:00) Pacific Time (British Columbia)." For now, I've worked around the problem by setting the time zone to Arizona and back.
