duration() function

duration() converts a value to a duration type.

duration() treats integers and unsigned integers as nanoseconds. For a string to be converted to a duration type, the string must use duration literal representation.

Function type signature
(v: A) => duration
For more information, see Function type signatures.

Parameters

v

(Required) Value to convert.

Examples

Convert a string to a duration

duration(v: "1h20m")// Returns 1h20m

Convert numeric types to durations

duration(v: 4800000000000)

// Returns 1h20m
duration(v: uint(v: 9600000000000))// Returns 2h40m

Convert values in a column to durations

Flux does not support duration column types. To store durations in a column, convert duration types to strings.

data
    |> map(fn: (r) => ({r with _value: string(v: duration(v: r._value))}))

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.
