Yes, you can.
The time of primary in assigned to 0 by default.
In fact you can see in source.f the following line:
  AGESTK (NPFLKA) = +ZERZER

Now, for instance, you can replace that line with the following
ones:

  CALL FLNRRN (RGAUSS)
  AGESTK (NPFLKA) = RGAUSS*1.0D-12

The call to FLNRRN returns a pseudo-random number RGAUSS sampled
from a normal gaussian distribution

In such a way you the time of injection of your
primaries will be normally distributed with
mean = 0 and sigma = 1 ps
