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.
