Candlestick data are different

Alpaca Market Data

I am using the get_barset of alpaca API in Python. After several investigation I realized that the created candlestick(1-min) are total different to other sources. Is alpaca using a different timeframe like:
10:30:20 to 10:31:20 instead of 10:30:00 to 10:31:00

I had a look into the candlestick chart in the Paper Trading account of alpaca and this chart is implemented by Trading View and is also total different to my candlestick chart drawn by Python. There is no problem with the drawing of the candlestick, following the data are different.

I posted a similar question (if not the same) yesterday under the posting title “Alpaca Minute Bar Data”. But no response yet. Not sure if that is how slow the Alpaca response time is.
