InfluxQL date and time functions

Use InfluxQL date and time functions to perform time-related operations.

now()

Returns the current system time (UTC). Supported only in the WHERE clause.

now()

time()

Used in the GROUP BY clause to group data into time-based intervals, also known as “windows”, using the specified interval. Timestamps in the time column are updated to the start boundary of the window they’re in and grouped by time. Windows use preset round-number boundaries based on the specified interval that are independent of time conditions in the WHERE clause.

This operation can be used to do the following:

  • Downsample data by aggregating multiple points in each window into a single point per window.
  • Normalize irregular time series data to occur at regular intervals.

Supported only in the GROUP BY clause.

time(interval[, offset])

Arguments

  • interval: Duration literal that specifies the window interval.
  • offset: Duration literal that shifts preset time boundaries forward or backward. Can be positive or negative. Default is 0s.
Examples

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.
