Year zero problem when applying asset package

[TheodoreRakel]

I am using Pro 2.2.2 and trying to run the GP tool 'apply asset package' and load data.  I get the following error that 'year 0 is out of range'.  Is there any way to find out what date is causing this problem?  I looked at the data in the asset package and all the dates I find are from Sep 2018.  If I run 'apply asset package' and do not load the data, then the GP successfully completes.

This looks like a timestamp in the UN that is causing the issue. This error occurs when reading the UN (though that doesn't explain why you don't get the error when not loading data).

I submitted a case to esri about this and found that the connection I was using when running the 'Apply Asset Package' GP tool needed to have its geodatabase connection properties set to use 'Traditional' versioning.  I had it set to use 'Branch' versioning.  I ended up deleting the Utility Network dataset and running 'Stage Utility Network' GP tool again.  Then I ran 'Apply Asset Package' and loaded the data successfully.
