Time Travel

Browser extension that spoofs the date, time, and time zone websites see

Browser extensionfree

Time Travel is a free, open-source browser extension for Chrome and Firefox that spoofs the current date, time, and time zone as seen by JavaScript on any website, without changing the system clock. It's for developers and QA testers who need to verify date-dependent behavior — like expiring trials, scheduled content, or time-zone-sensitive logic — without manually adjusting their whole computer's clock.
