System time
===========

My SGI IRIS Indigo (that computer from 1991 which has a 33MHz MIPS CPU)
does not use the NTP protocol to synchronise its time. I keeps its time
locally  (its RTC  chip  is supported  by a  Tadiran  battery which  is
soldered in). I do not have any type of clock on the desktop nor in the
terminal so I normally don't care about time here. So I never noticed
how is the clock precision.

I use this computer to browse the gopherspace, to write short texts and
programs, and to play with old SGI  tools so I don't need to care about
the time, actually.

But today I  noticed that the VCal (a small  nice Motif calendar) shows
incorrect day. So I issued the "date" command and fond that is is about
23 hours late.

I have set the correct time in 2017 and then have not touched is. So is
23 hour normal or too much? I have no idea.
