Feature request: arbitrary input format for date

[Jaka Kranjc]

Hi,
the "pure numbers" input support in date is very limited. The info page 
suggests only YYYYMMDD, HHMM and HH are accepted. It would be nice if date 
could work with (practically) any format, the same way it can for the output.

Example:
$ date -u -d 20080210155848
date: invalid date `20080210155848'

Wanted:
$ date -u -i +%Y%m%d%H%M%S -d 20080210155848
Sun Feb 10 15:58:48 CET 2008
$ date -u -i +%Y%m%d%H%M%S -d 20080210155848 +%H
15

The -i is, of course, just a suggestion, the implementation details are 
irrelevant to me.

Thanks for your good work & bye!
