Need to get 4 Hrs back time and compare with successive time

Hi all,

I am working on a script in which i need to get 4 hrs back time from the current time which i got from this perl function :

`perl -e 'print localtime(time() - 14400) . "\n"'`

now i need to get this in a loop and increment that time by 15 minutes
i.e
i=900(=15minutes)
`perl -e 'print localtime(time() - 14400+$i) . "\n"'`
I do not know perl much and the above code does not work . i have to compare time from a table column from a database which has a listing afer every 15 minutes . so basically i hv to get a loop in which i can use this function and compare the time which is exactly after every 15 minutes. there is a new lisitng in the Db after every 15 minutes and i need to check the time gap.

How can I compare time from this perl function or if there is any other script it will be really appreciated .

Thanks,
Manik

CHECK-ZONE-EXPIRATION(1p)				User Contributed Perl Documentation				 CHECK-ZONE-EXPIRATION(1p)

NAME

       check-zone-expiration

SYNOPSIS

       # check-zone-expiration dnssec-tools.org paypal.com dnssec-tools.org    will expire in 26 days, 2 hours, 16 minutes, 36 seconds paypal.com
       will expire in 12 days, 17 hours, 7 minutes, 1 second

       # check-zone-expiration -m 1123200 dnssec-tools.org paypal.com paypal.com	  will expire in 12 days, 17 hours, 6 minutes, 22 seconds

DESCRIPTION

       The check-zone-exiration script reports how long until a zone will expire by querying for the zone's (top level) RRSIG and calculating how
       much time is left before the signatures will no longer be valid.  It will then report how much time is left in human readable form.

       If the -m switch is provided with a time argument (in seconds), it will only print output for zones that have less than that time left.

OPTIONS

       -m STRING
       --minimum-reporting=STRING
	   Minimum reporting time, or else be silent for the zone
