[aprssig] Wanted perl time code

[Bruce Kreutzer]

Andrew-

Perl has loads of time functionality.  The solution depends on what format
the date you have is in.  There is also very good perl documentation
online.  For example, google perl time diff.
I found this page as an overview:  http://www.perl.com/lpt/a/718

You can just subtract times in internal format:   $difftime = time() -
$prevtime;
Then print it using gmtime() to extract the individual values like this:
my @z = gmtime($difftime);
print "It has been $z(3) days, $z(2) hours, $z(1) minutes, $z(0) seconds
since we last heard xxxx";

(I haven't tried to actually run this code, but it should work).

There may be easier/better/faster ways to write this, but it's readable,
more or less.

I can't answer the mysql question.
