"The HTTP-based Memento framework bridges the present and past Web by interlinking current resources with resources that encapsulate their past. It facilitates obtaining representations of prior
states of a resource, available from archival resources in Web archives or version resources in content management systems, by leveraging the resource's URI and a preferred datetime. To this end, the
framework introduces datetime negotiation (a variation on content negotiation), and new Relation Types for the HTTP Link header aimed at interlinking resources with their archival/version resources.
It also introduces various discovery mechanisms that further support briding the present and past Web."

More on converting between different date/time formats and the effective range of the formats.

New URN schemes with no central minting authority. duri allows you to name a resource that was identified by the specified URI at the specified date (e.g. refers to the IETF's homepage at the end of
the year 2001). tdb allows you to name a physical object or entity that was described by a resource that was identified by a specified URI at the specified date (e.g. refers to IETF the orginization
as referenced by their homepage at the end of the year 2001). Date format is concise but I'd prefer RFC3339 rather than roping in another date format.

Starting on a new simple project I wanted to get the history of my Delicious links. Delicious has an export tool available via the settings section so I thought I'd try that. However, the links
aren't exported in XML not even in XHTML but rather in HTML. Shocking. An example:
"Don't Tase Me, Bro!" (UF Student Tasered Remix)
Remix of the 'Don't tase me, bro!' guy getting tasered.At this point I'm already not going to use this file because its in HTML but I'm even more disgusted by those date time values.
Raymond Chen of the Old New Thing posted about recognizing timestamps and timestamp sentinel values. From the first blog post and with the use of a calculator for base conversion one can tell that
those are UNIX style timestamps counting the number of seconds since 1970.
It reminds me of my hatred for the MIME date time format I developed working on my webpage's server side parsing of atom and RSS. Atom is
of course my favorite as Atom uses the Internet date time format described in the following documents. Here's an example of one
On the other hand the evil and villainous RSS uses the MIME date time format now described in the more
recent IETF MIME standard. Here's an example

The Internet date time format has the advantage of being so easy to sort. An alphabetic sort with normal C-style collation rules of strings containing Internet date times will also sort them
chronologically. This is not the case for the MIME date time due to the preceding day of the week and the spelled out month name. This also means that when producing these you have to figure out
the day of the week and when parsing them you have to match month names rather than just parsing out numbers. Anyway now days if I see mention of a date time in a new proposed standard or spec I be
sure to point out the numerous advantages of the Internet date time format.
