RECENT
The RECENT filter is used to restrict the time range to a span relative to the current time.
The syntax is RECENT(<span>)
The span is a human-readable string describing the span of time. For example, '1 day', '7 days', '30 minutes' are all valid values.
You can also specify a 'from' time. For example, '1 day from 00:00:00' will give you the last 24 hours from midnight. Note that these times are in UTC rather than in local time, so you'll need to adjust for your timezone
