# Reporter template authoring and report filters

> Reporter PDF templates use HTML source, report filters use operator objects, and date_time uses the runtime local time zone.

September 1, 2026Documentation correctionAction required

## Affects

***

Teams that create Reporter templates, generate reports through the API, or use the `date_time` template tag.

## What changed

***

Reporter PDF output is authored as HTML in the `.tpl` source and converted during generation. The create-report example now uses the required filter-operator object and no longer includes unsupported `ledgerId`. The `date_time` tag uses the Reporter runtime's local time zone, not UTC.

These are documentation corrections of current behavior; they do not announce a runtime release.

## Impact

***

**Classification: Action required.**

## What you need to do

***

**Step 1**

Use HTML source for PDF templates, update report requests to use filter operators, and review output that assumed UTC timestamps.

### Deadline

Update before the next report-generation deployment.
