experimental.subDuration() function

The experimental.subDuration() function is subject to change at any time. By using this function, you accept the risks of experimental functions.

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

This function will be removed once duration vectors are implemented. See influxdata/flux#413.

import "experimental"

    d: 12h,
    from: now(),



The duration to subtract.


The time to subtract the duration from. Use an absolute time or a relative duration. Durations are relative to now().


Subtract six hours from a timestamp

import "experimental"

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

// 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
