Usage of　に、とき, ときに
* At Christmas, I bought...
  * During Christmas, I bought...
  * During Christmas time, I bought...

There aren't any significant differences in the English sentences above.
**They mean the same thing.** Much the same case for your sentences. とき is a
shortened form of ときに, which is a more explicit and completely unambiguous
version of に.

In your scenario, the temporal use of に is extremely clear. But there may be
other situations where the meaning of に (since it's a particle with a lot of
meanings) is a bit ambiguous, and you might want to swap it for ときに **to be
extra clear in communication.**
