G'day alen129,

Firstly, this was crossposted: http://stackoverflow.com/questions/39499429/perl-cgi-date-and-time-picker-with-auto-populate-with-current-date-and-time. While it's OK to do this, it's considered polite to inform us to avoid duplication of effort.

I plugged "Perl CGI Date and Time picker" into my search engine and got many results. Have you tried this? "add date picker in cgi page" (from PerlMonks) was high on the list of results.
