I've emailed the author of the module, but it's possible that the problem doesn't lie in there. I'm working on a mail archiving script, that takes everything modified yesterday and stuffs it in a directory. Seems easy enough, but Date::EzDate seems to be jumping the gun by one hour. 
use Date::EzDate;
$now = Date::EzDate->new("feb 28 2003 10:59 PM");
$i=0;
while ($i<120) {
    print("$now->{'epochday'}, $now->{'full'} \n");
    $i++;
    $now->{'epochsecond'}+=1;
}

I've tried this with 'adjust for DST' turned on and off, no change. I'm running Windows 2000 SP3, ActivePerl Build 631. I've had the same results on three similarly configure machines. I've checked SuperSearch here, and the mailing lists on Activestate.com. Any ideas, or other things I could check? Maybe something not using EzDate?
