Time-based filtering is also a feature offered to us by the Graph API. Its usefulness is much the same as that of limiting the number of requests, only that instead of simply limiting the number of responses, it allows us to perform our filtering based on the time that the objects were created or updated.
The Facebook platform is much more geared towards time-oriented information, with features like the News and Home Feed connections, so this type of filtering makes a lot of sense for applications that would display this information.
Time-based results can be filtered to those results that are either before or up to a specific time. By combining both the until and since properties, we can achieve filtering for a date range.
