I'm not saying it is; but you asserted that "the strftime-option gets 
ignored totally in 1.8.6", and I don't see any evidence of that so far.

What you need to do is to make a smallest-possible test case. Keep 
trimming code out of your program until it stops demonstrating the 
problem. In the process of doing this, you will probably discover for 
yourself where the problem lies and how to work around it. If you can't, 
then at least you'll have a simple test case which can be used by others 
to reproduce it.

We can't run your code as it is, because we don't have the mysql 
database it depends on; and even if we did, we probably couldn't be 
bothered setting it up unless you've first demonstrated that mysql *is* 
an essential part of reproducing your issue.

Just glancing at your code I can see it does some weird things:

        t = Time.now.strftime("%Y-%m-%d %H").to_i
#       t = Time.now
        print t.to_s + "\n"
        t2 = t.to_i - 3600
        t2 = Time.at(t2)
        print t2.to_s + "\n"
        t3 = t2.to_s.slice! 0..12
        print t3.to_s + "\n"

That strftime line is just a very strange way of extracting the year 
(only) from the time:

>> t = Time.now.strftime("%Y-%m-%d %H")
=> "2010-05-11 14"
>> t.to_i
=> 2010

You haven't even shown us what those print lines show. Are they what you 
expect?  If not, what do you see, and what did you expect to see? Or is 
the problem occurring later on in the code?
