The DateTimeFilter custom transformer allows you to filter features based on a date/time attribute.

It supports multiple filtering modes to test whether an entity’s date value falls before, after, within, or around specified ranges.

Functionality

The transformer evaluates the value of a selected DateTime attribute (in FME Date/Time format) against user-defined conditions.

Depending on the chosen filter type, features are routed to either:

Passed: if the feature’s date meets the filter condition.

Failed: if the feature’s date does not meet the filter condition.

Filter Types

After Date: features with dates strictly after the specified date.

Before Date: features with dates strictly before the specified date.

Between Dates: features with dates between two specified dates (inclusive).

From Date + Duration: features with dates occurring after a given start date, for a specified duration (in minutes).

Until Date - Duration: features with dates occurring before a given end date, within a specified duration (in minutes).

Around Date (± Duration): features with dates falling within a symmetric window around a given date (± duration in minutes).
