I have the following code to copy some files from one place to another for post processing. Basically what it does get the current time and copies the files from the previous hour. 
#!/usr/bin/perl

$hr = (localtime(time))[2];

if ($hr == 0)
{
   $hr = 23;
   @tdate = localtime(time - 86400);
}
else
{
   $hr -= 1;
   @tdate = localtime(time);
}
$day  = $tdate[3];
$mon  = $tdate[4] + 1;
$yr  = $tdate[5] + 1900;

$fname = sprintf("files.%4d%02d%02d%02d*.gz", $yr, $mon, $day, $hr);

`cp /foo/$fname /bar/`;

Everything is working just fine. It grabs the date and everything, but my concern is how to handle Daylight Savings Time? When DST goes back 1 hr I'll end up processing the same files twice and when it moves forward 1 hr I'll end up skipping an hour of files. Any ideas will be appreciated. Thanks for your wisdom.
