# clocksync **Explanation** The clocksync NDM is a system NDM designed to detect situations where a flow source is sending flows to Netography with timestamps that are out of sync with Netography’s clock. Bad timestamps can make network events hard to correlate with each other. **What to Look For** Examine the configuration of the device sending flows to determine if its clock is set properly. Also check network time settings on the device to make sure that the device clock is kept in sync with a valid network time server. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
