Hi Andrew,

Thanks. This patch is working. We'd like to stay up to date with EPICS releases but have no immediate plans for 3.15.
Is it feasible to include this into a 3.14.12.6 release?

There was a change committed to the 3.15 branch of Base before 3.15.1 to
make the NTP time provider adjust automatically to changes in the system
clock tick rate. Changing the tick rate after iocInit is not advisable,
but in your case this change may be all you need. Since you're evidently
using a 3.14.12 release of Base you should be able to apply the attached
patch file to your copy.

HTH,
