Description

Change Timezone (Time Shift) is an extension that let you easily and quickly change your timezone to the desired value and protect your privacy. Simply open the addon options page and select a desired timezone from the drop-down list. Once a timezone is selected, adjust the name and value fields if needed. Then reload all tabs for changes to take effect. Please note that this addon takes into account the daylight saving time. If you want to turn off the addon, simply click on the toolbar icon once (the icon color will turn to light grey). By default, the addon is active (the toolbar icon has dark grey color). To report bugs, please fill out the bug report form on the addon's homepage (https://mybrowseraddon.com/change-timezone.html).

Worked well until daylight savings time ended. Now every time is off by an hour, and there were no answers to support requests. Seems like this is no longer being maintained.

BE CAREFUL WITH USING THIS. I list my 250 day duolingo streak because of this extension, which shifted my time forward. Even after I uninstalled, the time shift was still there. Give instructions to uninstall this piece of garbage

It simply does not change anything. Not my Whatsapp Web times. Not my Browser history (which I mostly use when I log my days. It's wrong. Changed it to my country's time. Still same.). Not anything. simply doesn't work

Sorry, it doesn't work. The following line (by specification) should set the hour value according to the local timezone. When this extension is active, it still uses the real OS timezone. new Date(new Date().setHours(0, 0, 0, 0)) Fri Oct 23 2020 06:00:00 GMT+0000 (Etc Greenwich Standard Time)

Does not work properly in all cases. I live in UTC-5, changed my TZ to UTC-8, open the debug console and type: new Date('2020-11-25T08:00:00Z').toISOString(). The time isn't the same as the argument to the Date function. That should match.

Doesn't work for JS devs, it's easier (and better in case u are a JS dev) to change your timezone from Windows datetime. Be aware of the interaction between JS and Windows Datetime or you'll be mad!!

BEWARE: This plugin completely breaks date inputs on websites. Examples: https://demos.telerik.com/aspnet-mvc/datepicker https://jqueryui.com/datepicker/ These aren't the only ones, just two examples. Any basic date input that has vanilla validation will not work right.

This addon don't take into account Daylight saving time. Only the last changes to the settings page are saved in memory.

Not terrible, seems to somewhat work, but upon testing it myself I've noticed it regularly leaks my actual timezone. (or the one that is selected in settings)

It does the job of changing timezone very well. However, beware if using a calendar or booking site. Calendars are messed up and could lead to mistakes.

Caused double-timezone issues, -4 became -8... Not sure why, but this did not do what I expected.

It'd have been 5 start, but i must ask why do you need access to browsing history. Otherwise, it does it's job well
