Usage: - Open the tab you want to change the time in. - Click the Extensions icon in the toolbar, then click Time Travel. - Choose a date from the calendar and edit the time if necessary, or enter a date and time directly (see examples below). - Confirm with Enter or by clicking the "Change Date" button. - Any JavaScript Date or Intl.DateTimeFormat in the current tab now returns the fake date/time you set. Other tabs and origins are not affected. To restore the system time, click the extension icon and switch off the "Enable Fake Date" toggle. When the fake date is enabled, the clock runs forward from the configured time. You can stop the clock by switching on the "Stop Clock" toggle. The fake date will be reset to the last value you set. To change the time zone, open "Options", enable "Change Time Zone" and select a time zone from the dropdown. When enabled, both Date objects and Intl.DateTimeFormat will use this time zone instead of the system time zone. The fake date in the Time Travel UI is still shown and configured in the system time zone, but a preview of the time in the configured time zone plus the Daylight Saving Time (DST) offset is shown if applicable. Example Dates and Formats: - 2025-04-27 12:40 - Local time - 2025-03-30 00:59:55 - Assuming your system time zone is Europe/London (GMT), 5 seconds before a one-hour jump to 2 a.m. (summer time) - 2025-04-27T12:40Z - Set local equivalent for given UTC time - 2025-04-27T12:40+1130 - Set local equivalent for time with +11:30 time zone offset. Note that actual time zone is not changed - 2025-03-25T12:40:00.120 - Local time with milliseconds - 1731493140025 - UNIX timestamp Features: - Fakes date and time for all methods of Date and Intl.DateTimeFormat objects. - (experimental) Time zone can be changed, with full support for DST transitions. - Time can be stopped and resumed. - Option to automatically reload page after changing date. - Only affects current tab after clicking the extension icon. Limitations: - Only JavaScript is affected by the extension. - Some functionality or animations may behave strangely if the clock is stopped. - The extension does not work in iframes with the sandbox attribute. This extension is open source software licensed under the MIT license. Contributions are welcome! If you have ideas, bug reports, or want to help improve Time Travel, please open an issue or submit a pull request on GitHub .
