Hey, I’m using the Polymarket market channel websocket (book + price_change events) to build a local orderbook. I’m noticing that the timestamps in the events are sometimes quite old compared to my local receive time — in some cases around 12–15 seconds behind. I’m currently looking at the btc-updown-5m markets. For reference, I’m comparing the event timestamp with my local receive timestamp (_received_at). Is this expected behavior for Polymarket websockets? Do the timestamps represent the original event creation time or something else? And would it be better to rely more on the local receive time instead? Would appreciate any insights from others working with the feed. Thanks!
