After Davros
From Tardis Wiki, the free Doctor Who reference
After Davros (AD) was a time scale which the Time Lords applied to the Genesis Incident, when the Fourth Doctor was sent to Skaro to interfere with Davros' creation of the Daleks at the end of the Thousand Year War. They placed this event as occuring in 34 AD. In relation to the Earth dating system, they placed Davros' life up to the Genesis Incident within ancient history, prior to the 2nd century.
