My computer at work, which has no internet connection, loses time -
about a minute or so every hour.  I have replaced the battery and
still no luck. I'm running Windows 98 and have had no luck thus far .
. any suggestions??

That sounds like the CMOS battery is dying.  On the motherboard there
is a small battery whose task is to keep time.  When it starts to run
out of power, those symptoms can occur.

I replaced the battery on the board - CR2032 - twice in fact .. no luck still . .

Linux has a utility which can be set up to automatically correct for
clock drift, which is normally very consistent in a given machine.

You have Win 98.  I suppose one could google for a utility which will
do the same thing for that OS, but have no idea if one exists.

A minute an hour almost certainly involves a part which has failed.

From what I can recall, on the older OSes (like Win'98), the OS would
only read the BIOS clock once upon bootup.  After that, it would rely
upon the CPU to keep accurate time.  Because the CPU clock's timer
does not mathematically match up with a real clock or the BIOS clock,
it would end up losing a few seconds each hour.

Thus, there's no real solution unless you either upgrade to a more
modern OS, or install some "catch-up" software that would instruct the
OS to read the BIOS clock on a regular basis.

Otherwise, reboot your computer once a day.  Just my 2cents...
