What's your opinion about the inclusion of the dateutil[1] extension in the standard library? [1] https://moin.conectiva.com.br/DateUtil

Gustavo,

+1000! I hadn't seen dateutil until today, but I think it is brilliant! Definitely fodder for the standard library.

The functionality is similar to a module that I wrote a few years back, though I didn't model the advanced behavior after the iCalendar RFC. Unfortunately, I have lost the fight to open source most of my work from that era, so I am more than happy to help review and assist in the effort to incorporate your excellent module into the standard library.

Some initial suggestion:

  1. relativedelta and maybe the tz module should be added to the datetime module.

  2. the tz module needs to be made Win32 aware -- at least minimally.
    It should also fail gracefully on systems that do not have /etc/localtime, /usr/share/zoneinfo, etc).

  3. Some of the constants like FREQ_* may be nicer without the FREQ_ prefix. I almost never use 'from x import *', so it seems unnecessary to protect the module namespace with prefixes (unless there is an existing collision that I do not see).

  4. Similarly, it would be useful to also support the long names for MO,TU,WE, etc.

I'm happy to supply patches as well.

Best regards, -Kevin Jacobs
