SCO Unix, ALR FlexCACHE losing time

[Vic Rice]

I have been running nbs_time from cron to keep my systems clock up to
date. Below is a piece of my clock log file:

12/27/90-06:00:56  Clock is 118 seconds slow.
12/27/90-06:02:54  New time set.

12/28/90-06:00:53  Clock is 63 seconds slow.
12/28/90-06:01:56  New time set.

12/29/90-06:00:53  Clock is 63 seconds slow.
12/29/90-06:01:56  New time set.

12/31/90-06:00:53  Clock is 104 seconds slow.
12/31/90-06:02:37  New time set.

01/01/91-06:00:53  Clock is 63 seconds slow.
01/01/91-06:01:56  New time set.

My system:    SCO ODT 1.0.0y (System V R3.2.1)
              ALR FlexCache 33/386
