The max anonymity is always default, i just think you are overparanoid with
the time in the case of streaming. Its not as if this would be stored in a
file ...
Also iam curious, can you point at a concrete case where knowing the exact
time of a system would significantly weaken its security?

there is nothing more to fear from them, then he is always stirring up
some war or other, in order that the people may require a leader. -- Plato
