Re: [MI400] MODMATR parameters

["Keith Carpenter" <CarpCon@xxxxxxx>]

Hi Mark,

I wanted to set the TOD for machine time syncronization purposes.
Currently I'm changing the sysval, but wanted to use the higher resolution
TOD/DTS format.

Problem:
I'm trying to use a SNTP client (MSNTP). It uses the
gettimeofday/settimeofday/adjtime functions.  These have the appropriate
resolution but apparently they're implimented as part of a "software" clock
and don't affect the machine clock. This clock instead uses/modifies an
"internal" offset to machine TOD.  Since most system time is derived from
the machine clock, this "software" clock is not that useful outside it's own
environment.

V4R2 introduced a couple of nice functions to convert between timeval and
_MI_Time formats (Qp0zCvtToTimeval and Qp0zCvtToMITime).  I figured to use
them to syncronize the machine TOD with the software clock.

Seems a MODTOD could have been introduced when MODMATR was blocked. Another
alternative might be to have a function to simply syncronize the machine TOD
to the "software clock".


Thanks all,
Keith
