There was no "2011-05-27 02:01:00" in Germany.
I am 100% sure nobody in Germany was on toilet on at this time.

At this date if you go at 01:59:00 and come back at 03:02:00 then you 
where 3 minutes on toilet but you was not at 2:01:00 because this time 
simply does not exist at this day.

This works as expected:

$ export TZ="Europe/Berlin"

$ date -d "2011-03-27 02:01:00"
date: invalid date `2011-03-27 02:01:00'

$ date -d "2011-03-26 02:01:00 tomorrow"
Sun Mar 27 03:01:00 CEST 2011
