now() function

now() is a function option that, by default, returns the current system time.

now() vs system.time()

now() returns the current system time (UTC). now() is cached at runtime, so all executions of now() in a Flux script return the same time value. system.time() returns the system time (UTC) at which system.time() is executed. Each instance of system.time() in a Flux script returns a unique value.

Function type signature
() => time

For more information, see Function type signatures.


Use the current UTC time as a query boundary

    |> range(start: -10h, stop: now())

Define a custom now time

option now = () => 2022-01-01T00:00:00Z

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
