[comp.sys.sun] 3/260 clock is slow

%melba.bby.OZ@uunet.uu.net (Gregory N. Bond) (03/16/89)

Sun 3/260, SunOs 3.5Export, (That's 50Hz power, if that's relevant)

The (real-time) clock on out 3/260 server is quite slow, losing around 5
mins/day.  This is a real problem as our application is somewhat
real-time.  Is there any way to tweak or speed up the real-time clock on
the server?  (We don't have the same problem on our 3/60's, they keep
pretty good time.)

Greg.

We had the same problem on our 3/280 server.  Sun replaced the board and
it's much better now.  They didn't know of any way to tweak the clock chip
and just said "it's a bad CPU board".

Our 3/280 used to do the same thing.  We got Sun to replace the CPU board
(we have a Sun service contract) and it got much better, although it still
keeps worse time than a $15 Timex.
