Re: Re-writing Genealogy::Gedcom::Date

Hi John

Thanx for your informative email.

Luckily my code is not intended to do any calculations. It simply 
accepts, parses and returns date strings - which must be provided in a 
given format.

I did read various parts from your references and understand they are 
complex for good reason. The whole topic is a marvellous example of a 
can of worms.

Regarding writing new code:

As for ISO 8601, I could buy a copy of the doc for $AUD235, or start 
with a similar standard, RFC 3339 for free.

As for the BNF on p 12 of RFC 3339, it resembles the BNF for "RFC4514: 
Lightweight Directory Access Protocol (LDAP): String Representation of 
Distinguished Names." [1] for which I have already written a 
Marpa::R2-based parser [2]. So, definitely doable, but fortuitously not 
needed at this point in time.
