# This is a test of the monkey patches in timezone_fixes.rb

# We use MailServerLogDone here just as a totally random model that has a datetime type.

# In Rails 3 the monkeypatch that these tests are testing is not necessary. So,
# since these tests are testing the Rails internals you could argue that they shouldn't
# be here. Well, you're right. But let's leave them in for the time being until the upgrade is finished.
# Then, we should probably delete this whole file
