public final class YYtime
- extends java.lang.Object
System.currentTimeMillis() may depend on the Network
Time Protocol (NTP). An adversary can change the packets, potentially
trying to set the time backwards, or keeping time fixed. This could all
be aimed at disrupting feralcore or applications running on top of
feralcore, such as yyrerandtrans. For this reason this class was created.
It wraps System.currentTimeMillis() in a call that makes sure that
time moves monotonically forward. If time fails to move forward then
it is an error.
We don't ever want the adversary to be able to rewind the time. So,
this class saves its notion of the time in a file on disk.
