EU BST-->GMT issue

Whenever I've tested the "fall back", I have to let it sit for over an hour - so set it to 11:59, let it roll over midnight, get to 1 am and then flip back to 12am.  The system knows it has to go through the 12am to 1am period twice - just setting it to roll over the first time, it doesn't seem to know to flip back.

If the roll over is at 2am, adjust this method accordingly.

If I manually set the time to 1 second after the reversion, it will set it to GMT, however, if I set it before the reversion time, and let it roll over said reversion time, it remains BST.

The first command below shows where I set it before rolling over reversion time, and the command at the end after all the date checks showing reversion did not occur is the command where I set it +1 second over reversion time, and it does set it to GMT.

That looks correct to me. The reversion occurs at 0100 UTC (which is to say 2am BST or 1am GMT), so wallclock times from 1am until 2am are repeated at the fall-back.

   Are there any known bugs revolving around the EU timezone not reverting from BST back to GMT?
