Re; Time Expiry Algorithm

/me shakes her head at Andrew Farmer.

Okay, now it's just ridiculous to suggest that you wouldn't be able to
implement a time limitation on something encrypted simply because
"clocks can be changed".

What 'clocks' are talking about -- which are you basing it off of?

What if you decided to code into the encryption the use of atomic
clocks, and include more than one or two as a redundancy/security
check?

Someone's really going create a huge conspiracy to change a few of the
world's atomic clocks drastically to be able to crack someone's
encrypted data? :P
