I just finished a debug session, single stepping through your code. I can see no system dependencies, time zone calculations all happen on the Perl level, based on a thing called the Olson Database. So the result cannot be system dependent.

The only thing I can imagine is happening, is that your initial $dt = DateTime->now value is not the same as it is for us, it appears to me (though I'm not absolutely sure) its value can depend on time zone information in the Registry, or in the TZ environment variable. Perhaps you'd better print it out, too, before you set the time zone.

Likely ikegami is right, and your computer's system clock isn't set correctly.
