PERL, Date & Time issues

Hello All,

This is my first script in PERL. Hence require your help in moving further.

I have a script which should populate the values for Today, Yesterday output.
For which I use timeFrame as a variable to obtain the time in hrs:mm as 10:00.

All I want is, I want my timeFrame to start with 00:00 and end with with my current timestamp. Say if the time is 07:23, my timeFrame should contain 00:00 to 07:00. [I am not bothered on Minutes since it works hourly basis]. I have written the PERL in the below way.

Code:
#!/usr/bin/perl
use Time::Local;
my %DataHash=();
$begOffset=3600*12;
my ($runYear, $runMonth, $runDay, $runHour, $runMin, $runSec) = (localtime(time))[5,4,3,2,1,0];
$runYear+=1900;
$runMin = (int($runMin/5)*5);
my $runTime = timelocal($runSec,$runMin,$runHour,$runDay,$runMonth,$runYear);
my $begTime = $runTime-$begOffset;
my $j=0;
for($i=$begTime;$i<=$runTime;$i+=3600){

        my $startTime = ($startHour,$startMin) = (localtime($i))[2,1];
        if ($startMin <10){$startMin="0$startMin";}
        if ($startHour <10){$startHour="0$startHour";}
        $timeFrame="$startHour:00";
        $DataHash{$j}->{'timeFrame'}=$timeFrame;
        $j++;
		print "TimeFrame -> $timeFrame StartTime -> $startTime  StartHour -> $startHour\n\n";
}

But the output came as
Quote:
TimeFrame -> 19:00 StartTime -> 2 StartHour -> 19

TimeFrame -> 20:00 StartTime -> 2 StartHour -> 20

TimeFrame -> 21:00 StartTime -> 2 StartHour -> 21

TimeFrame -> 22:00 StartTime -> 2 StartHour -> 22

TimeFrame -> 23:00 StartTime -> 2 StartHour -> 23

TimeFrame -> 00:00 StartTime -> 2 StartHour -> 00

TimeFrame -> 01:00 StartTime -> 2 StartHour -> 01

TimeFrame -> 02:00 StartTime -> 2 StartHour -> 02

TimeFrame -> 03:00 StartTime -> 2 StartHour -> 03

TimeFrame -> 04:00 StartTime -> 2 StartHour -> 04

TimeFrame -> 05:00 StartTime -> 2 StartHour -> 05

TimeFrame -> 06:00 StartTime -> 2 StartHour -> 06

TimeFrame -> 07:00 StartTime -> 2 StartHour -> 07
Now the current time is 07:23, so I want that output to be like below
Quote:
TimeFrame -> 00:00 StartTime -> 2 StartHour -> 00

TimeFrame -> 01:00 StartTime -> 2 StartHour -> 01

TimeFrame -> 02:00 StartTime -> 2 StartHour -> 02

TimeFrame -> 03:00 StartTime -> 2 StartHour -> 03

TimeFrame -> 04:00 StartTime -> 2 StartHour -> 04

TimeFrame -> 05:00 StartTime -> 2 StartHour -> 05

TimeFrame -> 06:00 StartTime -> 2 StartHour -> 06

TimeFrame -> 07:00 StartTime -> 2 StartHour -> 07
Can you please help me by correcting this code. It will be great if you make use of localtime and not anything else. Thanks in advance.

I am in a hurry, please help me asap. TA.
