[Realtime-feeds] Feed JSON field question

[Martinez, Eric]

Hi Matt,

The time field under features > properties corresponds to the *time at
which the earthquake occurred*.

The updated field under features > properties corresponds to the time the
most recent update arrived. This can be driven by any preferred associated
product (for example, the arrival of a ShakeMap product can affect the
updated property).

Updated earthquakes are *not* re-added to the past hour or past day feeds.
Each feed for a given time period contains earthquakes that occurred within
that time period. Subsequent updates to earthquake information do not
affect what earthquakes appear in the feeds.
