This is a little shorter and more confusing. 
  @local=(localtime(time+$off_h*60*60));
  @gmt=(gmtime(time+$off_h*60*60));
  $diff=$gmt[2]-$local[2] + ($gmt[5] <=> $local[5] 
                                     || 
                             $gmt[7] <=> $local[7])*24;

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
