Hi Team,
I’m using OPC UA Extractor to extract time series data from Honeywell PHD source system.
I have configured history in configuration for backfilling for 30days.But, i can see more historian data than expected please find the screenshot below.
I have used following configurations in history.
start-time: 0
end-time: 30d-ago
max-read-length:30d

Let me if this configuration is correct for fetching 30days previous day.
Please provide configuration if above one is wrong.
