There are two registry entries that control the time-synchronization blackout

in the same directory as the other ION Enterprise registry entries.
TimesyncBlackoutInterval_mins
Default value: 5
This entry is specified in minutes. It must have a value greater than 1 in order
for time-synchronization blackouts to occur. A value of 60 or greater configures
blackouts to occur once an hour.

TimesyncBlackoutDuration_secs
Default value: 150 (2 minutes 30 seconds in seconds)
This entry is specified in seconds. A value of 0 (zero) disables the blackout
feature. This entry cannot have a value greater than or equal to 3600 (one hour).

If you want to disable the blackout feature but keep time synchronization enabled, set the
TimesyncBlackoutDuration_secs register to 0.
TimesyncBlackoutDuration_secs register to 0.
There are certain settings for these registry entries that can disable time
synchronization in general (not just the blackout feature). These are as follows:
synchronization in general (not just the blackout feature). These are as follows:
TimecyncBlackoutInterval_mins < 1
TimesyncBlackoutDuration_secs >= 3600 (1 hour)
u TimesyncBlackoutDuration_secs (the value converted to minutes) >=
TimecyncBlackoutInterval_mins
Do not use any of these settings to disable time synchronization. If you want to
disable time synchronization for a particular device, use the ION Management
Console to do so.

When your values are bad, an error is sent to the system log database. If time
synchronization signals are not occurring, check the system log to see if there’s
an error message about your blackout values.

When reviewing time synchronization messages in the system log, remember
that the time in the message is not the time to which the meter was time
synched, but rather it is the time the message was posted to the system log. The
message is posted after the meter is time synched.
