I have already said this before and I will repeat this for the purposes of feedback.
Time packets do not need to be encrypted as not only do they not contain anything secret, even if you knew the contents they are useless anytime after the packet has been delivered. You do yourself a disfavor in encrypting something that is not worth encrypting. It takes processing overhead, increases packet size, and there is no gain in doing so. You need to justify encrypting something and please don't say that it is because some other document says to encrypt everything. I want to know what is the benefit from doing so, what are the risks in not doing so and what is the cost of doing so, particularly in loss of accuracy, increased error budget, etc. The whole thing is a bad idea from what I can tell.
