I don't know much about running remote commands, but the date part can be done using:

use DateTime qw( );
my $date = DateTime
           ->today( time_zone => 'local' )
           ->strftime( '%Y-%m-%d' );
[download]

or just

use POSIX qw( strftime );
my $date = strftime( '%Y-%m-%d', localtime );
[download]

Well, that's assuming the date is the date on which the cron job is run. Is it something else?
