Each page or screen within a FullStory session gets its page/screen start time from the user's browser. After capture begins, all raw events captured on the client side within the end user's browser or mobile app are captured with a relative timestamp offset from the start of capture.
Switching to absolute time
You can switch between the relative and absolute time during session playback by clicking the timestamp at the bottom. The timestamps displayed within FullStory's UI will always be based on your computer, device, or browser time, not the customer's timezone.
