Don't bother. It's just a default. 
You can enter whatever you want in randseed if so desired.

And as Jonas pointed out, you should not use FPC's Builtin random to begin with 
if you want really random numbers, because it is perfectly predictable.

In short: 
People interested in crypto grade randomness should use specialized routines, 
not the built-ins provided by FPC.
