In the context of a geocoder, a timestamp is a numerical value that represents a specific moment in time and is used to record when an event or action took place. It is often expressed in a standardized format, such as the number of seconds or milliseconds since the start of the Unix epoch (January 1, 1970). Timestamps are used to track changes and events in the geocoder, such as when a waypoint was added or a route was modified. This information can be used for a variety of purposes, such as monitoring the accuracy of location data, analyzing patterns in navigation, or tracking the history of changes to the geocoder. Timestamps are an essential component of geocoding systems and play an important role in ensuring the accuracy and reliability of location data.
