Haystack start.tz != end.tz hisError
If you get the below his error after changing the timezome in Niagara through Platform Administration > Change Date/Time, then you'll have to do the below steps to resolve it. These are for points being synchronized with Niagara his data.
Steps to resolve his error
The user will need to sync the point and his timezones in FIN Stack. On the Site in DB Builder, you'll want to pick the same timezone that is in Niagara and sync that to all points. (If this part doesn't work, ask support for hisRewrite)
Then run the job again.
Thats it, now all points and his data should have the same timezone as Niagara.
