As an aside:

# perl -e 'print time' will return the current time in Unix epoch form
+at

# So if you substract 43200, that should give you the current time min
+us 30 minutes in Unix epoch format:

time=$(perl -e 'print time-43200')

There are 86400 seconds in a day, so subtracting 43200 subtracts half a day. Subtract 1800 to go back half an hour.

c:\@Work\Perl\monks>perl -wMstrict -le
"my $t = time;
 print $t;
 print scalar localtime $t;
 print scalar localtime $t - 43200;
 print scalar localtime $t -  1800;
"
