experimental.subDuration() function

experimental.subDuration() is subject to change at any time.

experimental.subDuration() subtracts a duration from a time value and returns the resulting time value.


experimental.subDuration() is deprecated in favor of date.sub().

Function type signature
(d: duration, from: A, ?location: {zone: string, offset: duration}) => time where A: Timeable

For more information, see Function type signatures.



(Required) Time to subtract the duration from.

Use an absolute time or a relative duration. Durations are relative to now().


(Required) Duration to subtract.


Location to use for the time value.


Subtract six hours from a timestamp

import "experimental"

experimental.subDuration(from: 2019-09-16T12:00:00Z, d: 6h)// Returns 2019-09-16T06:00:00.000000000Z

Subtract six hours from a relative duration

import "experimental"

option now = () => 2022-01-01T12:00:00Z

experimental.subDuration(d: 6h, from: -3h)// Returns 2022-01-01T03:00:00.000000000Z

Subtract two days from one hour ago

A time may be represented as either an explicit timestamp or as a relative time from the current now time. subDuration can support either type of value.

import "experimental"

option now = () => 2021-12-10T16:27:40Z

experimental.subDuration(from: -1h, d: 2d)// Returns 2021-12-08T15:27:40Z

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.
