From 785b4c9fd5f60915778705efc0e949631233bfc9 Mon Sep 17 00:00:00 2001
From: Miod Vallat <miod@cvs.openbsd.org>

Subject: In the neverending tradition of never making things simple, SGI used
 1940 as the timebase on Indigo 2, but 1970 on Indy (verified with the `date'
 command at the PROM prompt and checking what values ended up in the DS1286).
 Indy will no longer be 30 years in the future from an IRIX point of view.
