Understanding Time Processed for Mixpanel Events

Hi Brian S., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support.

Based on the knowledge sources, "Time Processed (UTC)" is a default property that Mixpanel automatically collects on every event. It's represented in the raw data as mp_processing_time_ms and is defined as the "UTC timestamp in milliseconds when the event was processed by Mixpanel servers."This is different from when the event first reaches Mixpanel's API. There's another property called "API Timestamp" ($mp_api_timestamp_ms) which represents the "UTC timestamp in milliseconds when the event was received by our API."So to directly answer your question: "Time Processed" marks when the event was processed by Mixpanel servers, not when it first reaches Mixpanel's API (which would be captured by the API Timestamp property instead).Default Properties provides this information in their documentation about automatically collected properties.
