Editing a page results in no obvious error messages, but the changes never show up once editing is done. Revisions show that the changes have been stored, but when MoinMoin views the page in question, only an earlier, unedited revision is displayed.

## Where you think is this bug happening ? (general, plugin [plugin name], theme [theme name], ...

 * general

The problem occurred after changing the date and time of the server machine. The clock was incorrectly set an hour ahead (12:22pm), so a "date" command was issued in a terminal to set it to the proper time (11:22am). Once this happened, MoinMoin no longer displayed the last revisions of pages but instead the most recent revisions i.e. revisions that appear to have been made in the future. Thus, editing a page creates a revision whose created_at or similar field is earlier than other revisions, resulting in it not being displayed.

This is probably caused by the way MoinMoin chooses revisions to display. If MoinMoin picks the one created most recently (by created_at, etc. field), then this issue will continue to occur. If instead, MoinMoin were to choose the correct revision by greatest ID, time and date would not affect the choice.

== Steps to reproduce ==

Try it!

## Describe the steps needed to reproduce the bug. If we can't reproduce it, we  probably can't fix it.
 1. Setup a default MoinMoin server.
 1. Create and edit wiki pages.
 1. On the host, set the clock back an hour.
 1. Attempt to edit pages. Revisions will be created, but only the ones with the greatest creation field will be displayed.

## How to deal with the bug until it is fixed
Temporarily set the server's date forward, edit pages, then set the clock back to the current time.
