Assign the current time to the field provided by parameter
as
.
The time is represented as milliseconds since January 1, 1970
(UTC). In historical queries, the current time is when the query
is issued. In live queries, the current time is when
now()
is processed for each event. The
value, therefore, depends on where in the query
now()
is placed. If it is placed before the
first aggregate function, it is only evaluated the first time
the query sees the event. If it is placed after the first
aggregate function, it is evaluated continuously, and gives the
live value of the current system time, which can divert between
LogScale nodes.
