I had a problem with IPLing I think a year behind the current date.
This was running under VM. VM was IPL'd with the wrong date, passing
the date along to each guest. We had 5 DOS guests, one MVS guest, and
one VS1 guest at the time. This was our first conversion of one of
the DOS guests to MVS. I don't think there were any problems while
running a year back, but something led me to check the date, and I
discovered we had the wrong one. We shut everything down, and reIPL'd
VM with the correct date, and brought everything back up. The only
problem after coming back up was that anyone who had logged on TSO
while the date was 1 year behind couldn't log on. That was me, and a
few of the programmers and the operator.
This led to my getting my 2nd TSO id, which I wanted in the beginning,
but a girl who worked there for a while didn't want anyone to have 2
TSO ids. It so happened that she wasn't home, so I kind of sat there
and couldn't even log on for about an hour, until she finally got home
and called me. Then I logged on with her password and ID and reset my
own ID. Needless to say, it didn't take much convincing to get a 2nd
TSO id after that.

RACF has the capability of disallowing a user to logon if he's been
inactive for a certain number of days. We got stung by this at Clearing
long ago, when even STC wasn't allowed to logon. We installed an exit to
bypass that difficulty. I believe now that RACF has been altered such
that started tasks aren't limited in that fashion. We also had a proc
that could be started from the console to restore certain critical ID's
so we could recover from a similar disaster in the future. When we first
got stung, we were down for an entire CBOT trading session and the
repercussions were VERY MESSY, to say the least.
