opt-in: wrong time shown in reports module for opt-in related dates

[lazka]

Issue

Creating a report which shows opt-in related date/time files for related email
addresses shows them all off by one/two hours.

Expected Behavior

The report should show the right date/times

Actual Behavior

It shows all times off by one/two hours (local vs GMT)

Possible Fix

PR: #6488

Steps to Reproduce

1. Create a user and do a confirmed-opt-in
2. Create a report showing the opt-in fields
3. Compare the shown fields with the actual time when the actions took place

Context

We are trying to automate some things based on the opt-in state.
The wrong time and jumps on daylight saving transitions make this hard.
