When logging times, I use GMT.
strftime() is an expensive critter in terms of perforance. BUT, expensive is relative and often this does not matter. Use if it you want to. Other ways shown below. 
#!/usr/bin/perl -w
use strict;
use Time::Local;

# Sets the current time to 5 seconds past midnight on Oct 28, 2008.

my $start_time = timelocal(5,0,0,28,10-1,2008);
my $start_time_string = localtime($start_time);
print "Local time=$start_time_string\n";  #Tue Oct 28 00:00:05 2008

foreach my $delta_days (1..35)
{ 
   my $new_time = $start_time;
   $new_time = $start_time + ($delta_days*24*60*60);
   my $new_time_string = gmtime($new_time);
   print "$new_time_string\n";
}

__END__
