Time gradient
From Tardis Wiki, the free Doctor Who reference
Time gradients were the different gradients that different years or centuries had. Connecting the points could enable energy to be extracted.
The Time Eaters fed off the fluctuations in the time gradients. (AUDIO: Chronoclasm)
The Temparon's hourglass technology was based on time gradients. (AUDIO: The Hourglass Killers)
