#
# EXPLANATION OF THE TEST:
# The test checks if the histogram extension works well despite the
# ***timezone's hell***.
# For example the extension, for an user in the GMT+2 timezone, should count
# an event inserted on the 2011/12/24 at 1:30 AM as belonging to the day 24.
# The problem is that in the engine the events are inserted as UTC-relative:
# for the example our event is inserted for the day 2011/12/23 at 23:30 UTC.
# The Histogram extension must revert this when collecting data, and this test
# check this.
#
# ******************************************************************************
#
# In the test we create an event in the "borderline" time for the timezone and
# then we insert it in the engine as UCT-relative. After, we retrieve the data
# from the extension and finally we check that the event belong to the right day
