My key made with PGP shows this:

sub  4096R/10BFF302  created: 2006-04-06  expires: 2008-04-06  usage: E
sub  4096R/B3DF6DC0  created: 2008-04-06  expires: never       usage: E

So GPG will see the valid period on the second subkey as 2008-04-06 to never.
and not use it before 2008-04-06 ?

Can this enable me to set created date´s like, in 2010 if i want?

For me, creating a key is a one-time-thing, why not add some sub´s from
the start, so i dont have to mess with it later?

Isent theese algo settings stored with each uid? or do i mix things together?

Thanks for your help.
