    event: Fix changing the timezone
    
    g_date_time_equal() corrects for timezone offsets to ensure that, e.g.,
    6 AM CST is treated as equal to 12 PM UTC. This means attempts to change
    the start and end times of events to the same time in another timezone
    are currently failing. We need to remove this attempt at optimization
    since it's not doing the right thing.
