What it is: Event Time is now a selectable property in the derived property builder. You can pair it with any date-type user property to compute time differences: for instance, 'registration date - Event Time' gives you days since a user registered. Previously, Event Time wasn't available as an input here, so calculations like this required workarounds or lived outside Amplitude entirely.

Where: Data → Properties → Derived Properties. Event Time now appears as a selectable property in the derived property builder.

Who: All customers, including EUDC.

When: GA. Available now.
