Ohmigod! That means my dishwasher, dryer, refrigerator, microwave, toaster
and egg-timer are going to crash! DAMN YOU KENMORE!!
Folks, think.
How does the RCX use time? It uses it as an internal clock for operations.
Think of it as a metronome. It can display the time because a little hack
in the OS knows how to count hours, minutes and seconds from a given mark.
Are metronomes going to suddenly halt at midnight on Dec. 31st? (Well,
according to some cults they are, but that's a different matter).
If it is a serious concern to you, just do the test that many banks,
industries and agencies have done. Duplicate the process on a testbed
machine and set it's clock forward to Dec. 31, 1999.
And if you find a way to do that with an RCX. Let us know.
Aloha,
JR
