  We study the time-dependence of quantum entanglement between two Unruh-DeWitt
detectors, one at rest in a Minkowski frame, the other non-uniformly
accelerated in some specified way. The two detectors each couple to a scalar
quantum field but do not interact directly. The primary challenge in problems
involving non-uniformly accelerated detectors arises from the fact that an
event horizon is absent and the Unruh temperature is ill-defined. By numerical
calculation we demonstrate that the correlators of the accelerated detector in
the weak coupling limit behaves like those of an oscillator in a bath of
time-varying "temperature" proportional to the instantaneous proper
acceleration of the detector, with oscillatory modifications due to
non-adiabatic effects. We find that in this setup the acceleration of the
detector in effect slows down the disentanglement process in Minkowski time due
to the time dilation in that moving detector
