i tried the NOW() option

my $sth = $dbh->prepare("INSERT INTO network VALUES (\"$serial\", \"$interface\", \"NOW()\")") or die $DBI::errstr;
$sth->execute or die $DBI::errstr;

but the new record has a date|time of

Statistics::Basic::Median(3pm)				User Contributed Perl Documentation			    Statistics::Basic::Median(3pm)

Statistics::Basic::Median - find the median of a list SYNOPSIS
Invoke it this way: my $median = median(1,2,3); Or this way: my $v1 = vector(1,2,3); my $med = median($v1); And then either query the values or print them like so: print "The median of $v1: $med "; my $mq = $med->query; my $m0 = 0+$med; Create a 20 point "moving" median like so: use Statistics::Basic qw(:all nofill); my $sth = $dbh->prepare("select col1 from data where something"); my $len = 20; my $med = median()->set_size($len); $sth->execute or die $dbh->errstr; $sth->bind_columns( my $val ) or die $dbh->errstr; while( $sth->fetch ) { $med->insert( $val ); if( defined( $m = $med->query ) ) { print "Median: $m "; } # This would also work: # print "Median: $med " if $med->query_filled; } METHODS
new() The constructor takes a single array ref or a single Statistics::Basic::Vector as arguments. It returns a Statistics::Basic::Median object. Note: normally you'd use the median() constructor, rather than building these by hand using "new()". _OVB::import() This module also inherits all the overloads and methods from Statistics::Basic::_OneVectorBase. OVERLOADS
This object is overloaded. It tries to return an appropriate string for the calculation or the value of the computation in numeric context. In boolean context, this object is always true (even when empty). AUTHOR
